The idea is that you could have a system with multiple 85xx  
processors in it.  One can act as master and the others as slaves/ 
agents and lets say they are all connected over RapidIO.  Having  
LAWBAR0 free allows for the master to come in and setup a global  
memory map for the whole system.  John's probably got better details  
as I think that's what he did for the RapidIO based 85xx system he had.
