If you're using U-Boot as your Linux bootloader then probably the only thing you need to do is to pass your desired baud rate through the bootargs as follows: console=ttyS0,<baud_rate>
Here's my sample bootargs setting for 115200 baud rate: bootargs=root=/dev/nfs nfsroot=198.185.4.28:/home/visitor/exports/target ip=198.185.4.88:198.185.4.28:198.185.4.1:255.255.255.0:mytarget:eth2:off console=ttyS0,115200 ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
