Don't enable ECC.
Memory clearing is only done for correctness. ECC memory does not
work properly unless initialized.
I think the Opteron setup now is down to the minimal needed for
things to work. You only observe one reset correct?
YHLU: One reset is right, but the output of the very beginning is not neat.

As Ron mentioned later this needs a comment. In the general case we should
not be enabling bus master DMA by default. I tend to remove bus master
enables before remembering any special circumstances of the chip.
YHLU: but the code in amd8131_bridge.c and not in general code. (devices

Thanks that looks correct. And it was nice to see my changes were
that simple to follow.

Hmm. Can we throw in a sanity check to ensure we don't run out of heap?
I assume that is what was happening.
Does the 4-way s4880 work? I'm not quite certain how my changes would
YHLU: I will double check that, it not, need to increade the heap size
