Default Processor Memory Map

The default processor memory map that is valid at power-up or reset
remains in effect until reprogrammed for specific applications.
defines the entire default map ($00000000 to $FFFFFFFF).

1. Default map for PCI/ISA I/O space. Allows software to determine
whether the system is MPC105-based or Falcon/Raven-based by
examining either the PHB Device ID or the CPU Type register.
2. The first 1MB of ROM/Flash bank A (socketed 1MB ROM/Flash)
appears in this range after a reset if the rom_b_rv control bit in the
Falcon's ROM B Base/Size register is cleared. If the rom_b_rv control
bit is set, this address range maps to ROM/Flash bank B (soldered 4MB
or 8MB ROM/Flash).
