But still we have serial port settings like baudrate. BR2_TARGET_GENERIC_GETTY_BAUDRATE_x must match your serial port settings. So we're loosing flexibility of my approach here, but what is even more important imagine if there're 2 serial ports in the system and they have different baudrates but both properly described in kernel bootargs. With BR2_TARGET_GENERIC_GETTY only 1 console could be used then but not either of them. -Alexey
