Dear opembmcer,
I am green to openbmc and I want to learn something about ast2500.Now I have one board ast2500 and 
use openbmc code romulus.I know the default debug uart is uart5 and I want to change it to uart1,because
on my board, uart1 is rs232.I have tried these ,but not effective.
(1) set the hardware strap register bit29 0 on ast-g5.c
(2) set CONFIG_SYS_NS16550_COM1 from 0x1E784000 to 0x1E783000


Any addvice will be appricated.
                                             Thanks,
                                             JunHeng
