1. Programmable via the PHB's PCI Configuration registers. For the
MVME2400 series, RAM size is limited to 256MB.
2. To enabled the CHRP "io-hole", program the PHB to ignore the
0x000A0000 - 0x000FFFFF address range.
3. Programmable mapping via the four PCI Slave Images in the
Universe II ASIC.
4. Programmable mapping via the Special Slave Image (SLSI) in the
Universe II ASIC.
