Not sure if you should use pc_serial.h. If you look at include/asm-ppc/serial.h many boards
use their own definitions for this stuff. But probably this is OK for ceder.
Anyway,
#define BASE_BAUD ( 1843200 / 16 )
assumes that you use 1.843200 MHz clock for your UARTs.
As this is not the case for your custom board, you should change BASE_BAUD properly.
For this you could create your own header file and include it from include/asm-ppc/serial.h
(I don't think modifying pc_serial.h is a good idea).
Best regards,
Andrei
