Notes
1. Reserved for future larger FLASH devices.
2. The FLASH is logically one bank but may be physically implemented in two banks.
After RESET, the MPC8540 does not map any PCI memory space (inbound or outbound), and does not
respond to Config cycles.

VME Memory Map

The MVME3100 is fully capable of supporting both the PReP and the CHRP VME Memory Map
examples with RAM size limited to 2GB.
