Do you have all the other OF related defines in your u-boot config
file?
#define OF_CPU "PowerPC,[EMAIL PROTECTED]"
#define OF_SOC "[EMAIL PROTECTED]"
#define OF_TBCLK (bd->bi_busfreq / 8)
#define OF_STDOUT_PATH "/[EMAIL PROTECTED]/[EMAIL PROTECTED]"
Maybe you are not properly setting up entries in the flat device tree
passed to the kernel. So when the kernel takes over and re-initializes
the serial port the speed is all messed up.
Can you verify the flat device tree passed to the kernel is correct?
Specifically these properties:
timebase-frequency = <0>; // from bootloader
bus-frequency = <0>; // from bootloader
clock-frequency = <0>; // from bootloader
