The following table shows a recommended CHRP memory map from the 
point of view of the processor.

1. Programmable via Falcon chip set. For the MVME2300 series, 

RAM size is limited to 128MB and ROM/Flash to 4MB.

2. To enable the “Processor-hole” area, program the Falcon chip set to 

ignore 0x000A0000 - 0x000BFFFF address range and program the 
Raven to map this address range to PCI memory space.
