serial: msm-geni: don't rely on parent misc device commit 1b15483deb3f ("misc: add Qualcomm GENI SE QUP device driver") introduced support for platform-specific oversampling values, necessary to configure the UART clocks on all platforms at runtime. However it relies in probing a parent device. Despite the DM_FLAG_PRE_RELOC flag, this is not done consistently during boot. Instead, take another approach by relying on ofnode_ helpers to read the serial engine base address and do the read directly. This fixes early UART on boards with a non-default oversampling rate.

serial: zynqmp: Fetch baudrate from dtb and update The baudrate configured in .config is taken by default by serial. If change of baudrate is required then the .config needs to changed and u-boot recompilation is required or the u-boot environment needs to be updated. To avoid this, support is added to fetch the baudrate directly from the device tree file and update. The serial, prints the log with the configured baudrate in the dtb. The commit c4df0f6f315c ("arm: mvebu: Espressobin: Set default value for $fdtfile env variable") is taken as reference for changing the default environment variable. The default environment stores the default baudrate value, When default baudrate and dtb baudrate are not same glitches are seen on the serial.

This functionality is disabled by default.

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

The most problematic one is enabling DEBUG_UART_PL011 based on PL01X_SERIAL(DM based) because debug console has type selection based on it. enum pl01x_type type = CONFIG_IS_ENABLED(DEBUG_UART_PL011) ? TYPE_PL011 : TYPE_PL010; Without it pl01x_generic_setbrg() is configuring different registers.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

serial: serial-uclass: Add generic serial RX buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

To avoid this, support is added to fetch the baudrate directly from the device tree file and update. The serial, prints the log with the configured baudrate in the dtb. The commit c4df0f6f315c ("arm: mvebu: Espressobin: Set default value for $fdtfile env variable") is taken as reference for changing the default environment variable. The default environment stores the default baudrate value, When default baudrate and dtb baudrate are not same glitches are seen on the serial.

This uses a static fixed UART port configuration selected via Kconfig options and dedicated print functions from debug_uart.h. This is useful e.g. when debugging problems so early during boot, that not even the DM is initialized at that point, and thus DM_SERIAL is not available either. This functionality is disabled by default. To activate it, define the following Kconfig options and select SCIF type using CFG_SCI/CFG_SCIF_A/ CFG_HSCIF/<nothing for regular SCIF>: CONFIG_DEBUG_UART=y CONFIG_DEBUG_UART_SCIF=y CONFIG_DEBUG_UART_BASE=0xe6540000 CONFIG_DEBUG_UART_CLOCK=24000000 The later two options define the SCIF physical base address and SCIF input clock in Hz.

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode. Some BootROM of MediaTek's SoCs will change the UART into high-speed mode and the U-Boot must use this driver to initialize the UART.

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

However it relies in probing a parent device. Despite the DM_FLAG_PRE_RELOC flag, this is not done consistently during boot. Instead, take another approach by relying on ofnode_ helpers to read the serial engine base address and do the read directly. This fixes early UART on boards with a non-default oversampling rate.

If change of baudrate is required then the .config needs to changed and u-boot recompilation is required or the u-boot environment needs to be updated. To avoid this, support is added to fetch the baudrate directly from the device tree file and update. The serial, prints the log with the configured baudrate in the dtb. The commit c4df0f6f315c ("arm: mvebu: Espressobin: Set default value for $fdtfile env variable") is taken as reference for changing the default environment variable. The default environment stores the default baudrate value, When default baudrate and dtb baudrate are not same glitches are seen on the serial.

Kconfigs: Correct default of "0" on hex type entries It is not a parse error to have a default value of "0" for a "hex" type entry, instead of "0x0". However, "0" and "0x0" are not treated the same even by the tools themselves. Correct this by changing the default value from "0" to "0x0" for all hex type questions that had the incorrect default. Fix one instance (in two configs) of a default of "0" being used on a hex question to be "0x0". Remove the cases where a defconfig had set a value of "0x0" to be used as the default had been "0".

x86: Allow locating the UART from ACPI tables When coreboot does not pass a UART in its sysinfo struct, there is no easy way to find it out. Since coreboot does not actually init the serial device when serial is disabled, it is not possible to make it add this information to the sysinfo table. Add a way to obtain this information from the DBG2 ACPI table, which is normally set up by coreboot. For now this only supports a memory-mapped 16550-style UART.

serial: msm-geni: correct oversampling value based on QUP hardware revision Starting from QUP v2.5 the value of oversampling is changed from 32 to 16, keeping the old value on newer platforms results on wrong set UART IP clock divider, thus the asked baudrate does not correspond to the actually set with all the consequencies for a user. The change links the driver to a new Qualcomm GENI SE QUP driver to get its hardware version and update the oversampling value. Deliberately the code under CONFIG_DEBUG_UART_MSM_GENI is not touched, since a wanted baudrate can be controlled by setting a modified CONFIG_DEBUG_UART_CLOCK build time variable.

serial: sh: Add DEBUG_UART support Add support for debug output very early during boot using the DEBUG_UART mechanism. This uses a static fixed UART port configuration selected via Kconfig options and dedicated print functions from debug_uart.h. This is useful e.g. when debugging problems so early during boot, that not even the DM is initialized at that point, and thus DM_SERIAL is not available either. This functionality is disabled by default. To activate it, define the following Kconfig options and select SCIF type using CFG_SCI/CFG_SCIF_A/ CFG_HSCIF/<nothing for regular SCIF>: CONFIG_DEBUG_UART=y CONFIG_DEBUG_UART_SCIF=y CONFIG_DEBUG_UART_BASE=0xe6540000 CONFIG_DEBUG_UART_CLOCK=24000000 The later two options define the SCIF physical base address and SCIF input clock in Hz.

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

It means to be able to enable debug console you also need to enable driver itself. That's why add all dependecies and list only debug consoles which are enabled based on driver selection to avoid compilation error when user asks for certain debug console but driver is not enable for it.

serial: atmel_usart: Use fixed clock value in SPL version with DM_SERIAL This patch adds an alterative SPL version of atmel_serial_enable_clk(). This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

serial: Add serial driver for Intel MID Add a specific serial driver for Intel MID platforms. It has special fractional divider which can be programmed via UART_PS, UART_MUL, and UART_DIV registers. The UART clock is calculated as UART clock = XTAL * UART_MUL / UART_DIV The baudrate is calculated as baud rate = UART clock / UART_PS / DLAB Initialize fractional divider correctly for Intel Edison platform. For backward compatibility we have to set initial DLAB value to 16 and speed to 115200 baud, where initial frequency is 29491200Hz, and XTAL frequency is 38.4MHz.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: msm-geni: don't rely on parent misc device commit 1b15483deb3f ("misc: add Qualcomm GENI SE QUP device driver") introduced support for platform-specific oversampling values, necessary to configure the UART clocks on all platforms at runtime. However it relies in probing a parent device. Despite the DM_FLAG_PRE_RELOC flag, this is not done consistently during boot. Instead, take another approach by relying on ofnode_ helpers to read the serial engine base address and do the read directly. This fixes early UART on boards with a non-default oversampling rate.

This uses a static fixed UART port configuration selected via Kconfig options and dedicated print functions from debug_uart.h. This is useful e.g. when debugging problems so early during boot, that not even the DM is initialized at that point, and thus DM_SERIAL is not available either. This functionality is disabled by default. To activate it, define the following Kconfig options and select SCIF type using CFG_SCI/CFG_SCIF_A/ CFG_HSCIF/<nothing for regular SCIF>: CONFIG_DEBUG_UART=y CONFIG_DEBUG_UART_SCIF=y CONFIG_DEBUG_UART_BASE=0xe6540000 CONFIG_DEBUG_UART_CLOCK=24000000 The later two options define the SCIF physical base address and SCIF input clock in Hz.

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

serial: serial-uclass: Add generic serial RX buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

If change of baudrate is required then the .config needs to changed and u-boot recompilation is required or the u-boot environment needs to be updated. To avoid this, support is added to fetch the baudrate directly from the device tree file and update. The serial, prints the log with the configured baudrate in the dtb. The commit c4df0f6f315c ("arm: mvebu: Espressobin: Set default value for $fdtfile env variable") is taken as reference for changing the default environment variable. The default environment stores the default baudrate value, When default baudrate and dtb baudrate are not same glitches are seen on the serial.

serial: sh: Add DEBUG_UART support Add support for debug output very early during boot using the DEBUG_UART mechanism. This uses a static fixed UART port configuration selected via Kconfig options and dedicated print functions from debug_uart.h. This is useful e.g. when debugging problems so early during boot, that not even the DM is initialized at that point, and thus DM_SERIAL is not available either. This functionality is disabled by default. To activate it, define the following Kconfig options and select SCIF type using CFG_SCI/CFG_SCIF_A/ CFG_HSCIF/<nothing for regular SCIF>: CONFIG_DEBUG_UART=y CONFIG_DEBUG_UART_SCIF=y CONFIG_DEBUG_UART_BASE=0xe6540000 CONFIG_DEBUG_UART_CLOCK=24000000 The later two options define the SCIF physical base address and SCIF input clock in Hz.

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ARM: uniphier: support Debug UART For ARM32 architecture, CONFIG_DEBUG_LL is available for early low-level debugging (and actually UniPhier 32bit SoCs use it), but ARM64 architecture does not support it. Instead, CONFIG_DEBUG_UART is available as an architecture-independent debug facility. This commit supports it on all the UniPhier SoCs (including the new ARMv8 SoCs), which is very useful for new SoC bringups. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> |

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: sh: Add DEBUG_UART support Add support for debug output very early during boot using the DEBUG_UART mechanism. This uses a static fixed UART port configuration selected via Kconfig options and dedicated print functions from debug_uart.h. This is useful e.g. when debugging problems so early during boot, that not even the DM is initialized at that point, and thus DM_SERIAL is not available either. This functionality is disabled by default. To activate it, define the following Kconfig options and select SCIF type using CFG_SCI/CFG_SCIF_A/ CFG_HSCIF/<nothing for regular SCIF>: CONFIG_DEBUG_UART=y CONFIG_DEBUG_UART_SCIF=y CONFIG_DEBUG_UART_BASE=0xe6540000 CONFIG_DEBUG_UART_CLOCK=24000000 The later two options define the SCIF physical base address and SCIF input clock in Hz.

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

(ie, SPL/TPL options when SPL or TPL are not defined) This patch is not attempting to be a complete list of items, but more like low hanging fruit. In some instances, I wasn't sure of DM was required, so I simply made them SPL or TPL. This patch attempts to reduce some of the menuconfig noise by defining dependencies so they don't appear when not used. Signed-off-by: Adam Ford <aford173@gmail.com> |

serial: atmel_usart: Use fixed clock value in SPL version with DM_SERIAL This patch adds an alterative SPL version of atmel_serial_enable_clk(). This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

serial: MediaTek: add high-speed uart driver for MediaTek SoCs Many SoCs from MediaTek have a high-speed uart. This UART is compatible with the ns16550 in legacy mode. It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode. Some BootROM of MediaTek's SoCs will change the UART into high-speed mode and the U-Boot must use this driver to initialize the UART.

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

x86: Allow locating the UART from ACPI tables When coreboot does not pass a UART in its sysinfo struct, there is no easy way to find it out. Since coreboot does not actually init the serial device when serial is disabled, it is not possible to make it add this information to the sysinfo table. Add a way to obtain this information from the DBG2 ACPI table, which is normally set up by coreboot. For now this only supports a memory-mapped 16550-style UART.

serial: msm-geni: correct oversampling value based on QUP hardware revision Starting from QUP v2.5 the value of oversampling is changed from 32 to 16, keeping the old value on newer platforms results on wrong set UART IP clock divider, thus the asked baudrate does not correspond to the actually set with all the consequencies for a user. The change links the driver to a new Qualcomm GENI SE QUP driver to get its hardware version and update the oversampling value. Deliberately the code under CONFIG_DEBUG_UART_MSM_GENI is not touched, since a wanted baudrate can be controlled by setting a modified CONFIG_DEBUG_UART_CLOCK build time variable.

serial: sh: Add DEBUG_UART support Add support for debug output very early during boot using the DEBUG_UART mechanism. This uses a static fixed UART port configuration selected via Kconfig options and dedicated print functions from debug_uart.h. This is useful e.g. when debugging problems so early during boot, that not even the DM is initialized at that point, and thus DM_SERIAL is not available either. This functionality is disabled by default. To activate it, define the following Kconfig options and select SCIF type using CFG_SCI/CFG_SCIF_A/ CFG_HSCIF/<nothing for regular SCIF>: CONFIG_DEBUG_UART=y CONFIG_DEBUG_UART_SCIF=y CONFIG_DEBUG_UART_BASE=0xe6540000 CONFIG_DEBUG_UART_CLOCK=24000000 The later two options define the SCIF physical base address and SCIF input clock in Hz. Optionally, to validate DEBUG_UART works, enable the following as well to get early serial output message by default: CONFIG_DEBUG_UART_ANNOUNCE=y Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org> |

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

serial: Add missing Kconfig dependencies for debug consoles Debug console is the part of serial driver in the same file. It means to be able to enable debug console you also need to enable driver itself. That's why add all dependecies and list only debug consoles which are enabled based on driver selection to avoid compilation error when user asks for certain debug console but driver is not enable for it.

serial: atmel_usart: Use fixed clock value in SPL version with DM_SERIAL This patch adds an alterative SPL version of atmel_serial_enable_clk(). This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode.

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

serial: Add serial driver for Intel MID Add a specific serial driver for Intel MID platforms. It has special fractional divider which can be programmed via UART_PS, UART_MUL, and UART_DIV registers. The UART clock is calculated as UART clock = XTAL * UART_MUL / UART_DIV The baudrate is calculated as baud rate = UART clock / UART_PS / DLAB Initialize fractional divider correctly for Intel Edison platform. For backward compatibility we have to set initial DLAB value to 16 and speed to 115200 baud, where initial frequency is 29491200Hz, and XTAL frequency is 38.4MHz.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

x86: Allow locating the UART from ACPI tables When coreboot does not pass a UART in its sysinfo struct, there is no easy way to find it out. Since coreboot does not actually init the serial device when serial is disabled, it is not possible to make it add this information to the sysinfo table. Add a way to obtain this information from the DBG2 ACPI table, which is normally set up by coreboot. For now this only supports a memory-mapped 16550-style UART.

The change links the driver to a new Qualcomm GENI SE QUP driver to get its hardware version and update the oversampling value.

serial: sh: Add DEBUG_UART support Add support for debug output very early during boot using the DEBUG_UART mechanism. This uses a static fixed UART port configuration selected via Kconfig options and dedicated print functions from debug_uart.h. This is useful e.g. when debugging problems so early during boot, that not even the DM is initialized at that point, and thus DM_SERIAL is not available either. This functionality is disabled by default. To activate it, define the following Kconfig options and select SCIF type using CFG_SCI/CFG_SCIF_A/ CFG_HSCIF/<nothing for regular SCIF>: CONFIG_DEBUG_UART=y CONFIG_DEBUG_UART_SCIF=y CONFIG_DEBUG_UART_BASE=0xe6540000 CONFIG_DEBUG_UART_CLOCK=24000000 The later two options define the SCIF physical base address and SCIF input clock in Hz.

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

serial: ns16550: Add RX interrupt buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX interrupt buffer support for NS16550 style UARTs. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

The change links the driver to a new Qualcomm GENI SE QUP driver to get its hardware version and update the oversampling value.

serial: sh: Add DEBUG_UART support Add support for debug output very early during boot using the DEBUG_UART mechanism. This uses a static fixed UART port configuration selected via Kconfig options and dedicated print functions from debug_uart.h. This is useful e.g. when debugging problems so early during boot, that not even the DM is initialized at that point, and thus DM_SERIAL is not available either. This functionality is disabled by default. To activate it, define the following Kconfig options and select SCIF type using CFG_SCI/CFG_SCIF_A/ CFG_HSCIF/<nothing for regular SCIF>: CONFIG_DEBUG_UART=y CONFIG_DEBUG_UART_SCIF=y CONFIG_DEBUG_UART_BASE=0xe6540000 CONFIG_DEBUG_UART_CLOCK=24000000 The later two options define the SCIF physical base address and SCIF input clock in Hz.

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

serial: add uart driver for MediaTek MT7620 SoC This patch adds uart support for MediaTek MT7620 and earlier SoCs. The UART used by MT7620 is incompatible with the ns16550a driver. All registers of this UART have different addresses. A special 16-bit register for Divisor Latch is used to set the baudrate instead of the original two 8-bit registers (DLL and DLM). The driver supports of-platdata which is useful for tiny SPL. Reviewed-by: Stefan Roese <sr@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Weijie Gao <weijie.gao@mediatek.com> |

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

For example, if the serial module was implemented in FPGA. Serial initialization is prohibited to run until the FPGA was programmed. This commit is to adding nulldev serial driver. This will allows the default console to be specified as a nulldev.

serial: serial-uclass: Add generic serial RX buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

debug_uart: Support board-specific UART initialisation Some boards need to set things up before the debug UART can be used. On these boards a call to debug_uart_init() is insufficient. When this option is enabled, the function board_debug_uart_init() will be called when debug_uart_init() is called. You can put any code here that is needed to set up the UART ready for use, such as set pin multiplexing or enable clocks.

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

This uses a static fixed UART port configuration selected via Kconfig options and dedicated print functions from debug_uart.h. This is useful e.g. when debugging problems so early during boot, that not even the DM is initialized at that point, and thus DM_SERIAL is not available either. This functionality is disabled by default. To activate it, define the following Kconfig options and select SCIF type using CFG_SCI/CFG_SCIF_A/ CFG_HSCIF/<nothing for regular SCIF>: CONFIG_DEBUG_UART=y CONFIG_DEBUG_UART_SCIF=y CONFIG_DEBUG_UART_BASE=0xe6540000 CONFIG_DEBUG_UART_CLOCK=24000000 The later two options define the SCIF physical base address and SCIF input clock in Hz.

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

serial: add uart driver for MediaTek MT7620 SoC This patch adds uart support for MediaTek MT7620 and earlier SoCs. The UART used by MT7620 is incompatible with the ns16550a driver. All registers of this UART have different addresses. A special 16-bit register for Divisor Latch is used to set the baudrate instead of the original two 8-bit registers (DLL and DLM).

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

serial: serial-uclass: Add generic serial RX buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

serial: add uart driver for MediaTek MT7620 SoC This patch adds uart support for MediaTek MT7620 and earlier SoCs. The UART used by MT7620 is incompatible with the ns16550a driver. All registers of this UART have different addresses. A special 16-bit register for Divisor Latch is used to set the baudrate instead of the original two 8-bit registers (DLL and DLM).

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

serial: serial-uclass: Add generic serial RX buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

serial: add uart driver for MediaTek MT7620 SoC This patch adds uart support for MediaTek MT7620 and earlier SoCs. The UART used by MT7620 is incompatible with the ns16550a driver. All registers of this UART have different addresses. A special 16-bit register for Divisor Latch is used to set the baudrate instead of the original two 8-bit registers (DLL and DLM). The driver supports of-platdata which is useful for tiny SPL. Reviewed-by: Stefan Roese <sr@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Weijie Gao <weijie.gao@mediatek.com> |

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it.

serial: serial-uclass: Add generic serial RX buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

You can put any code here that is needed to set up the UART ready for use, such as set pin multiplexing or enable clocks.

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

serial: ns16550: Add RX interrupt buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX interrupt buffer support for NS16550 style UARTs. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

serial: Add missing Kconfig dependencies for debug consoles Debug console is the part of serial driver in the same file. It means to be able to enable debug console you also need to enable driver itself. That's why add all dependecies and list only debug consoles which are enabled based on driver selection to avoid compilation error when user asks for certain debug console but driver is not enable for it.

serial: atmel_usart: Use fixed clock value in SPL version with DM_SERIAL This patch adds an alterative SPL version of atmel_serial_enable_clk(). This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode.

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

serial: Add serial driver for Intel MID Add a specific serial driver for Intel MID platforms. It has special fractional divider which can be programmed via UART_PS, UART_MUL, and UART_DIV registers. The UART clock is calculated as UART clock = XTAL * UART_MUL / UART_DIV The baudrate is calculated as baud rate = UART clock / UART_PS / DLAB Initialize fractional divider correctly for Intel Edison platform. For backward compatibility we have to set initial DLAB value to 16 and speed to 115200 baud, where initial frequency is 29491200Hz, and XTAL frequency is 38.4MHz.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

Kconfig: Varios: Fix more SPL, TPL dependencies Several options are presenting themselves on a various boards where the options are clearly not used. (ie, SPL/TPL options when SPL or TPL are not defined) This patch is not attempting to be a complete list of items, but more like low hanging fruit. In some instances, I wasn't sure of DM was required, so I simply made them SPL or TPL. This patch attempts to reduce some of the menuconfig noise by defining dependencies so they don't appear when not used. Signed-off-by: Adam Ford <aford173@gmail.com> |

serial: atmel_usart: Use fixed clock value in SPL version with DM_SERIAL This patch adds an alterative SPL version of atmel_serial_enable_clk(). This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode.

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

serial: MediaTek: add high-speed uart driver for MediaTek SoCs Many SoCs from MediaTek have a high-speed uart. This UART is compatible with the ns16550 in legacy mode. It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode. Some BootROM of MediaTek's SoCs will change the UART into high-speed mode and the U-Boot must use this driver to initialize the UART.

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

arm: zynqmp: Add ZynqMP minimal R5 support Xilinx ZynqMP also contains dual Cortex R5 which can run U-Boot. This patch is adding minimal support to get U-Boot boot. U-Boot on R5 runs out of DDR with default configuration that's why DDR needs to be partitioned if there is something else running on arm64. Console is done via Cadence uart driver and the first Cadence Triple Timer Counter is used for time. This configuration with uart1 was tested on zcu100-revC.

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

serial: Add additional depencies for PL010 and PL011 drivers Both of these drivers are implemented with and without DM that's why more symbols should be handled. The most problematic one is enabling DEBUG_UART_PL011 based on PL01X_SERIAL(DM based) because debug console has type selection based on it. enum pl01x_type type = CONFIG_IS_ENABLED(DEBUG_UART_PL011) ? TYPE_PL011 : TYPE_PL010; Without it pl01x_generic_setbrg() is configuring different registers.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

serial: serial-uclass: Add generic serial RX buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

serial: Add serial driver for Intel MID Add a specific serial driver for Intel MID platforms. It has special fractional divider which can be programmed via UART_PS, UART_MUL, and UART_DIV registers. The UART clock is calculated as UART clock = XTAL * UART_MUL / UART_DIV The baudrate is calculated as baud rate = UART clock / UART_PS / DLAB Initialize fractional divider correctly for Intel Edison platform. For backward compatibility we have to set initial DLAB value to 16 and speed to 115200 baud, where initial frequency is 29491200Hz, and XTAL frequency is 38.4MHz.

There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: dm: Add support for puts Some serial drivers can be vastly more efficient when printing multiple characters at once. Non-DM serial has had a puts option for these sorts of drivers; implement it for DM serial as well. Because we have to add carriage returns, we can't just pass the whole string directly to the serial driver. Instead, we print up to the newline, then print a carriage return, and then continue on. This is less efficient, but it is better than printing each character individually. It also avoids having to allocate memory just to add a few characters. Drivers may perform short writes (such as filling a FIFO) and return the number of characters written in len. We loop over them in the same way that _serial_putc loops over putc. This results in around sizeof(void *) growth for all boards with DM_SERIAL. The full implementation takes around 140 bytes.

serial: Add semihosting driver This adds a serial driver which uses semihosting calls to read and write to the host's console. For convenience, if CONFIG_DM_SERIAL is enabled, we will instantiate a serial driver. This allows users to enable this driver (which has no physical device) without modifying their device trees or board files. We also implement a non-DM driver for SPL, or for much faster output in U-Boot proper. There are three ways to print to the console: Method Baud ================== ===== smh_putc in a loop 170 smh_puts 1600 smh_write with :tt 20000 ================== ===== These speeds were measured using a 175 character message with a J-Link adapter. For reference, U-Boot typically prints around 2700 characters during boot on this board. There are two major factors affecting the speed of these functions. First, each breakpoint incurs a delay. Second, each debugger memory transaction incurs a delay. smh_putc has a breakpoint and memory transaction for every character. smh_puts has one breakpoint, but still has to use a transaction for every character. This is because we don't know the length up front, so OpenOCD has to check if each character is nul. smh_write has only one breakpoint and one memory transfer. DM serial drivers can only implement a putc interface, so we are stuck with the slowest API. Non-DM drivers can implement puts, which is vastly more efficient. When the driver starts up, we try to open :tt. Since this is an extension, this may fail. If it does, we fall back to smh_puts. We don't check :semihosting-features, since there are nonconforming implementations (OpenOCD) which don't implement it (but *do* implement :tt). Some semihosting implementations (QEMU) don't handle READC properly. To work around this, we try to use open/read (much like for stdin) if possible. There is no non-blocking I/O available, so we don't implement pending. This will cause __serial_tstc to always return true. If CONFIG_SERIAL_RX_BUFFER is enabled, _serial_tstc will try and read characters forever. To avoid this, we depend on this config being disabled.

serial: atmel_usart: Use fixed clock value in SPL version with DM_SERIAL This patch adds an alterative SPL version of atmel_serial_enable_clk(). This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99). Tested on socfpga_cyclone5_socrates. Signed-off-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> |

serial: MediaTek: add high-speed uart driver for MediaTek SoCs Many SoCs from MediaTek have a high-speed uart. This UART is compatible with the ns16550 in legacy mode. It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode. Some BootROM of MediaTek's SoCs will change the UART into high-speed mode and the U-Boot must use this driver to initialize the UART.

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: Add a SERIAL config At present we have SPL_SERIAL and TPL_SERIAL but not piain SERIAL. This works because there is a special build rule in Makefile that always includes the drivers/serial directory. It is better to have all driver directories included by drivers/Makefile and there is already a rule in there for this purpose. It just needs a Kconfig for U-Boot proper, so add one. It is always enabled, for now, since that mimics the current behaviour. It should be possible to drop the strange 'SERIAL_PRESENT' option at some point and use SERIAL instead.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it.

serial: Make full device search optional Commit 608b0c4ad4e5ec0c ("serial: Use next serial device if probing fails") added code to search for more serial devices if the default one was not probed correctly. Unfortunately, that breaks omap3_evm. So while investigating why that is the case, let's disable the full search for everyone but bcm283x where it is needed.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

sunxi: fix the default value of CONS_INDEX on non-A23/A33 SUN8I Only A23/A33 in SUN8I want a default value of CONS_INDEX of 5, for other chips the default value is 1 like other Allwinner SoCs. Fix this default value. The original wrong value has lead to wrong console on H3 Orange Pi boards.

serial: Add serial driver for Intel MID Add a specific serial driver for Intel MID platforms. It has special fractional divider which can be programmed via UART_PS, UART_MUL, and UART_DIV registers. The UART clock is calculated as UART clock = XTAL * UART_MUL / UART_DIV The baudrate is calculated as baud rate = UART clock / UART_PS / DLAB Initialize fractional divider correctly for Intel Edison platform. For backward compatibility we have to set initial DLAB value to 16 and speed to 115200 baud, where initial frequency is 29491200Hz, and XTAL frequency is 38.4MHz.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: Add a SERIAL config At present we have SPL_SERIAL and TPL_SERIAL but not piain SERIAL. This works because there is a special build rule in Makefile that always includes the drivers/serial directory. It is better to have all driver directories included by drivers/Makefile and there is already a rule in there for this purpose. It just needs a Kconfig for U-Boot proper, so add one. It is always enabled, for now, since that mimics the current behaviour. It should be possible to drop the strange 'SERIAL_PRESENT' option at some point and use SERIAL instead.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

arm: zynqmp: Add ZynqMP minimal R5 support Xilinx ZynqMP also contains dual Cortex R5 which can run U-Boot. This patch is adding minimal support to get U-Boot boot. U-Boot on R5 runs out of DDR with default configuration that's why DDR needs to be partitioned if there is something else running on arm64. Console is done via Cadence uart driver and the first Cadence Triple Timer Counter is used for time. This configuration with uart1 was tested on zcu100-revC.

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

sunxi: fix the default value of CONS_INDEX on non-A23/A33 SUN8I Only A23/A33 in SUN8I want a default value of CONS_INDEX of 5, for other chips the default value is 1 like other Allwinner SoCs. Fix this default value. The original wrong value has lead to wrong console on H3 Orange Pi boards.

serial: Add serial driver for Intel MID Add a specific serial driver for Intel MID platforms. It has special fractional divider which can be programmed via UART_PS, UART_MUL, and UART_DIV registers. The UART clock is calculated as UART clock = XTAL * UART_MUL / UART_DIV The baudrate is calculated as baud rate = UART clock / UART_PS / DLAB Initialize fractional divider correctly for Intel Edison platform. For backward compatibility we have to set initial DLAB value to 16 and speed to 115200 baud, where initial frequency is 29491200Hz, and XTAL frequency is 38.4MHz.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it.

serial: Make full device search optional Commit 608b0c4ad4e5ec0c ("serial: Use next serial device if probing fails") added code to search for more serial devices if the default one was not probed correctly. Unfortunately, that breaks omap3_evm. So while investigating why that is the case, let's disable the full search for everyone but bcm283x where it is needed.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: atmel_usart: Use fixed clock value in SPL version with DM_SERIAL This patch adds an alterative SPL version of atmel_serial_enable_clk(). This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99). Tested on socfpga_cyclone5_socrates. Signed-off-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> |

serial: MediaTek: add high-speed uart driver for MediaTek SoCs Many SoCs from MediaTek have a high-speed uart. This UART is compatible with the ns16550 in legacy mode. It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode. Some BootROM of MediaTek's SoCs will change the UART into high-speed mode and the U-Boot must use this driver to initialize the UART.

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: add uart driver for MediaTek MT7620 SoC This patch adds uart support for MediaTek MT7620 and earlier SoCs. The UART used by MT7620 is incompatible with the ns16550a driver. All registers of this UART have different addresses. A special 16-bit register for Divisor Latch is used to set the baudrate instead of the original two 8-bit registers (DLL and DLM). The driver supports of-platdata which is useful for tiny SPL. Reviewed-by: Stefan Roese <sr@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Weijie Gao <weijie.gao@mediatek.com> |

PL011 UART IP is SBSA compliant and firmware does the serial port set-up, initialization and let the kernel use UART port for sending and receiving characters. Normally software talk to one serial port time but some LayerScape platform require all the UART devices enabled in Linux for various use case.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

serial: ns16550: Add RX interrupt buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX interrupt buffer support for NS16550 style UARTs. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: atmel_usart: Use fixed clock value in SPL version with DM_SERIAL This patch adds an alterative SPL version of atmel_serial_enable_clk(). This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99). Tested on socfpga_cyclone5_socrates. Signed-off-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> |

serial: MediaTek: add high-speed uart driver for MediaTek SoCs Many SoCs from MediaTek have a high-speed uart. This UART is compatible with the ns16550 in legacy mode. It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode. Some BootROM of MediaTek's SoCs will change the UART into high-speed mode and the U-Boot must use this driver to initialize the UART.

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX interrupt buffer support for NS16550 style UARTs. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

bcm2835_pl011_serial: Add BCM2835 specific serial driver On bcm2835 we need to ensure we only access serial devices that are muxed to the serial output pins of the pin header. To achieve this for the pl011 device, add a bcm2835 specific pl011 wrapper device that does this check but otherwise behaves like a pl011 device. Signed-off-by: Alexander Graf <agraf@suse.de> |

One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

U-Boot on R5 runs out of DDR with default configuration that's why DDR needs to be partitioned if there is something else running on arm64. Console is done via Cadence uart driver and the first Cadence Triple Timer Counter is used for time. This configuration with uart1 was tested on zcu100-revC.

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: atmel_usart: Use fixed clock value in SPL version with DM_SERIAL This patch adds an alterative SPL version of atmel_serial_enable_clk(). This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99). Tested on socfpga_cyclone5_socrates. Signed-off-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> |

serial: MediaTek: add high-speed uart driver for MediaTek SoCs Many SoCs from MediaTek have a high-speed uart. This UART is compatible with the ns16550 in legacy mode. It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode. Some BootROM of MediaTek's SoCs will change the UART into high-speed mode and the U-Boot must use this driver to initialize the UART.

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: atmel_usart: Use fixed clock value in SPL version with DM_SERIAL This patch adds an alterative SPL version of atmel_serial_enable_clk(). This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode.

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

serial: Add serial driver for Intel MID Add a specific serial driver for Intel MID platforms. It has special fractional divider which can be programmed via UART_PS, UART_MUL, and UART_DIV registers. The UART clock is calculated as UART clock = XTAL * UART_MUL / UART_DIV The baudrate is calculated as baud rate = UART clock / UART_PS / DLAB Initialize fractional divider correctly for Intel Edison platform. For backward compatibility we have to set initial DLAB value to 16 and speed to 115200 baud, where initial frequency is 29491200Hz, and XTAL frequency is 38.4MHz.

There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX interrupt buffer support for NS16550 style UARTs. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it.

serial: serial-uclass: Add generic serial RX buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

serial: serial-uclass: Add generic serial RX buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

serial: serial-uclass: Add generic serial RX buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

serial: serial-uclass: Add generic serial RX buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

serial: serial-uclass: Add generic serial RX buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

debug_uart: Support board-specific UART initialisation Some boards need to set things up before the debug UART can be used. On these boards a call to debug_uart_init() is insufficient. When this option is enabled, the function board_debug_uart_init() will be called when debug_uart_init() is called.

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

serial: serial-uclass: Add generic serial RX buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX buffer support for all DM based serial drivers. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

debug_uart: Support board-specific UART initialisation Some boards need to set things up before the debug UART can be used. On these boards a call to debug_uart_init() is insufficient. When this option is enabled, the function board_debug_uart_init() will be called when debug_uart_init() is called. You can put any code here that is needed to set up the UART ready for use, such as set pin multiplexing or enable clocks.

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

serial: ns16550: fix debug uart putc called before init If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99).

They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

serial: ns16550: Add RX interrupt buffer support Pasting longer lines into the U-Boot console prompt sometimes leads to characters missing. One problem here is the small 16-byte FIFO of the legacy NS16550 UART, e.g. on x86 platforms. This patch now introduces a Kconfig option to enable RX interrupt buffer support for NS16550 style UARTs. With this option enabled, I was able paste really long lines into the U-Boot console, without any characters missing.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org> |

Convert all of CONFIG_CONS_INDEX to Kconfig This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

Revert "serial: ns16550: Add RX interrupt buffer support" This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881. As Bin Meng has tested and pointed out, we don't need the RX interrupt for the RX buffer support at all. Just reading all available characters into a buffer is sufficient to solve the problem with the dropped characters upon long lines pasted into the U-Boot prompt. Since this RX buffer support can be implemented in a generic way, without any device specifica (e.g. for the ns16550), I'll post a new patch with a new serial RX buffer support for DM, which all DM based serial drivers can use.

ns16550: add generic binding to unify the drivers Add generic binding to unify ns16550 drivers. There are several drivers using almost the same code, such as serial_dw, serial_keystone, serial_omap, serial_ppc, serial_rockchip, serial_tegra.c, and serial_x86. But each is platform specific. The key difference between these drivers is the way to get input clock frequency. With this unified approach, fixed clock frequency should be extracted from "clock-frequency" property of device tree blob. If this property is not available, the macro CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a function to get clock, eg, get_serial_clock().

dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port Currently the serial code assumes that there is always at least one serial port (and panics / crashes due to null pointer dereferences when there is none). This makes it impossible to use u-boot on boards where there is no (debug) serial port, because e.g. all uart pins are muxed to another function. This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which defaults to y (preserving existing behavior), which can be set to n on such boards to make them work. This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial, and is not necessary at this moment.

serial: Support an early UART for debugging This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org>
