Hi,
I found that there is a possible LAW conflict between SPD and 85xx default settings.
LAWBAR0 is used for DDR whereas LAWBAR1 for PCI1. But SPD initializes DDR LAW as LAWBAR1.
I think it could be a setup mess, right?
Agreed, however I do remember something about wanting to keep LAWBAR0 free always to allow an external agent to do things. Maybe Jon remembers more about that than I do.

Hmmm... I'm going to have to plead "getting old" ... :-) I don't recall anything special here...
It could be pure confusion, it could be with some hidden purpose. I just don't recall off hand. I seem to recall that there was a 0-based or a 1-based numbering issue too. I'd have to dig.

Jon, Kumar,
The original intent was to keep LAWBAR0 free to allow external agents to initialise a different Boot Rom Interface.
