[PATCH 1/2] configs: stm32mp1: set the console variable for extlinux.conf

[Patrick Delaunay]

Set the environment variable "console", used in extlinux.conf file when it
is generated by YOCTO distribution with:

UBOOT_EXTLINUX_CONSOLE ??= "console=${console},${baudrate}"

With these 2 variables, U-Boot give dynamically the used console and
baudrate in the Linux kernel bootargs.

For the STMicroelectronics boards, the used console is ttySTM0.

[PATCH 2/2] configs: stm32mp1: Add support for baudrates higher than 115200 for st-link

[Patrick Delaunay]

On STMicroelectronics boards, the UART can reliably go up to
2000000 bauds when connected to the on-board ST-LINK-V2 for STM32MP15

Unfortunately U-Boot will fall back to 115200 unless higher rates are
declared via CONFIG_SYS_BAUDRATE_TABLE.

This patch add the support of higher baudrates on STMicroelectronics
boards with ST-LINK.
