CP3002-Specific Registers

The following registers are special registers which the CP3002 uses to watch the onboard
hardware special features and a number of CompactPCI control signals.
Normally, only the system uEFI BIOS uses these registers, but they are documented here for
application use as required.
Note ...
Take care when modifying the contents of these registers as the system uEFI
BIOS may be relying on the state of the bits under its control.
