Sorry for the delay, I just noticed this one while looking
through my inbox for pending patches.

I think we should first simplify things by moving things over
to use the generic DEBUG_UART_8250 code where the addresses
need to be specified in the .config. It's been on my list of
things to do for quite a while but I keep getting interrupted.

My guess is that if we do that, this patch is no longer
needed :) Yong, care to take a look at that?

Regards,

Tony
