common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: Remove common.h usage We can remove common.h from most cases of the code here, and only a few places need an additional header instead. Signed-off-by: Tom Rini <trini@konsulko.com>

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: Remove common.h usage We can remove common.h from most cases of the code here, and only a few places need an additional header instead. Signed-off-by: Tom Rini <trini@konsulko.com>

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: Remove common.h usage We can remove common.h from most cases of the code here, and only a few places need an additional header instead. Signed-off-by: Tom Rini <trini@konsulko.com>

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing.

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.

mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations The current implementations have some issues detecting the correct values: dqs_find_max() will return "last passing fieldval + 1" instead of "last passing fieldval". Also it will return "maxval + 1" in the case that all fieldvals are tested valid (without error). dqs_find_min() will not test the "lowest" value because of using ">" instead of ">=". This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

This patch now rewrites these functions to fix those issues. Also, this patch uses the same approach of a for loop in both functions making it easier to read and maintain. Since the variables are integers now, we can use min()/max(), which handles the wrap around case for fieldval=0: return (0 - 1).

mips: mt76x8: ddr_cal: Rename dqs_test_valid() to dqs_test_error() This function returns "-1" (true) upon error. So the function name does not match its implementation which is confusing. This patch renames the function to dqs_test_error() which makes the code easier to read. Also change the return type to bool and return "true" or "false".

mips: mtmips: rewrite lowlevel codes of mt7628 This patch rewrites the mtmips architecture with the following changes: 1. Move MT7628 soc parts into a subfolder. 2. Lock parts of D-Cache as temporary stack. 3. Reimplement DDR initialization in C language. 4. Reimplement DDR calibration in a clear logic. 5. Add full support for auto size detection for DDR1 and DDR2. 6. Use accurate CPU clock depending on the input xtal frequency for timer and delay functions. Note: print_cpuinfo() has incompatible parts with MT7620 so it's moved into mt7628 subfolder.
