Processor Memory Map

The following table describes a suggested CHRP Memory Map from the point of view of the

processor. This memory map is an alternative to the PREP memory map. Note: in all

recommended CHRP maps, the beginning of PCI Memory Space is determined by the end of

DRAM rounded up to the nearest 256MB-boundry as required by CHRP. For example, if

memory was 1G on the baseboard and 192MB on a mezzanine, the beginning of PCI memory

would be rounded up to address 0x50000000 (1G + 256M).
