[coreboot] Custom Denverton Board: UART Initialization issue.

[Balaji Sivakumar]

Hi Everyone,

I am currently working on a custom Denverton board similar to the Intel
Harcuvar board.  CAR is working and the ROM stage is executing.

There should be console output on UART0, but it does not appear to be
initializing. There is a logic analyzer connected directly to the SOC UART
pins and the internal pull up can be seen working during hard strap
sampling, but after strap sampling TX goes low and stays low.

I have tried configuring it as both HSUART and legacy UART with early
console init both disabled and enabled and nothing has worked. Is there
anything that could be preventing the UART from initializing?

Thanks

Balaji
