Processor Memory Map

The following table describes a suggested Memory Map from the point of view of the Processor.
The beginning of PCI Memory Space is determined by the end of DRAM rounded up to the
nearest 256 MB boundary. For example, if memory was 1G on the baseboard and 192 MB on
a mezzanine, the beginning of PCI memory would be rounded up to address 0x50000000 (1
GB + 256 MB).
