Changing console uart on Bayley Bay CRB

[Gailu Singh]

Hi Experts,

I have working console uart 0 on Baytrail CRB board. However I am trying to
change to uart 2 (J9B4) DB9 connector. I have changed
CONFIG_UART_FOR_CONSOLE=2 from menuconfig, cleaned and rebuild and flashed
coreboot but do not see any log on port 2. Is there any other changes
required apart from CONFIG_UART_FOR_CONSOLE ?
