Subject: configs: stm32mp1: set the console variable for extlinux.conf
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-logo.png?a=commitdiff_plain;h=806c4dd31532708d30dd82a5173232dccc73c81b;p=u-boot.git

configs: stm32mp1: set the console variable for extlinux.conf

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.
