 * 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
