* MPC8xx Internal Memory Map

* Copyright (c) 1997 Dan Malek (dmalek@jlc.net)

*
|
|
* The I/O on the MPC860 is comprised of blocks of special registers
|
|
* and the dual port ram for the Communication Processor Module.
|
|
* Within this space are functional units such as the SIU, memory
|
|
* controller, system timers, and other control functions. It is
|
|
* a combination that I found difficult to separate into logical
|
|
* functional files.....but anyone else is welcome to try. -- Dan
