+ *
+ * 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
