23 * Due to limiations imposed by legacy hardware (primaryily IDE controllers),
24 * the PrPMC750 carrier board operates using a PReP address map.
26 * From Processor (physical) -> PCI:
27 * PCI Mem Space: 0xc0000000 - 0xfe000000 -> 0x00000000 - 0x3e000000 (768 MB)
28 * PCI I/O Space: 0x80000000 - 0x90000000 -> 0x00000000 - 0x10000000 (256 MB)
29 * Note: Must skip 0xfe000000-0xfe400000 for CONFIG_HIGHMEM/PKMAP area
31 * From PCI -> Processor (physical):
32 * System Memory: 0x80000000 -> 0x00000000
