Fixes for Tyan s2880

[ron minnich]

OK, I have applied Yh Lu's patches for the most part. In almost all cases 
they are tyan 2880-specific. There are three things I can see that might 
affect others:

#ifdef some-variable 
no longer works in many places, it has to be
#if some-variable == 1

to work.


-  for the new config too, there is no longer a default for _RAMBASE, 
	due to PPC and K8 differences

raminit.c sees the following changes:

If this is trouble, let me know.

You are going to have to set _RAMBASE in your mainboard Config.lb now.
