config BAUDRATE

help
Select a default baudrate, where "default" has a driver-specific
meaning of either setting the baudrate for the early debug UART
in the SPL stage (most drivers) or for choosing a default baudrate
in the absence of an environment setting (serial_mxc.c).
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>

config DEBUG_UART
bool "Enable an early debug UART for debugging"
help
The debug UART is intended for use very early in U-Boot to debug
problems when an ICE or other debug mechanism is not available.
To use it you should:
- Make sure your UART supports this interface
- Enable CONFIG_DEBUG_UART
- Enable the CONFIG for your UART to tell it to provide this interface
(e.g. CONFIG_DEBUG_UART_NS16550)
- Define the required settings as needed (see below)
- Call debug_uart_init() before use
- Call debug_uart_putc() to output a character
Depending on your platform it may be possible to use this UART before
a stack is available.
If your UART does not support this interface you can probably add
support quite easily. Remember that you cannot use driver model and
it is preferred to use no stack.
You must not use this UART once driver model is working and the
serial drivers are up and running (done in serial_init()). Otherwise
the drivers may conflict and you will get strange output.

config ZYNQ_SERIAL
bool "Cadence (Xilinx Zynq) UART support"
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.

This driver supports the Cadence UART. It is found e.g. in Xilinx
Zynq/ZynqMP.
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.

help
Select this to enable UART support for MediaTek High-speed UART
devices. This driver uses driver model and requires a device
tree binding to operate.
The High-speed UART is compatible with the ns16550a UART and have
its own high-speed registers.
