Migrate CUSTOM_SYS_INIT_SP_ADDR to Kconfig using system-constants.h - Make all users of CUSTOM_SYS_INIT_SP_ADDR reference SYS_INIT_SP_ADDR - Introduce HAS_CUSTOM_SYS_INIT_SP_ADDR to allow for setting the stack pointer directly, otherwise we use the common calculation. - On some platforms that were using the standard calculation but did not set CONFIG_SYS_INIT_RAM_SIZE / CONFIG_SYS_INIT_RAM_ADDR, set them. - On a small number of platforms that were not subtracting GENERATED_GBL_DATA_SIZE do so now via the standard calculation. - CONFIG_SYS_INIT_SP_OFFSET is now widely unused, so remove it from most board config header files.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

ARM: mxs: Setup stack in JTAG mode In case the MX23/MX28 is switched into JTAG mode via the BootMode select switches, the BootROM bypasses the CPU core registers initialization. This in turn means that the Stack Pointer (SP) register is not set as it is in every other mode of operation, but instead is only zeroed out. To prevent U-Boot SPL from crashing in this obscure JTAG mode, configure the SP to point at the CONFIG_SYS_INIT_SP_ADDR if the SP is zeroed out. Note that in case the SP is already configured, we must preserve that exact SP value and must not modify it. This is important since in every other mode but the JTAG mode, the SPL returns into the BootROM and BootROM in turn loads U-Boot itself. If the SP were to be corrupted, the BootROM won't be able to continue it's operation after returned from SPL and the system would crash. Finally, add the JTAG mode switch identifier, so it's not recognised as Unknown mode.
