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.
