6 * and the dual port ram for the Communication Processor Module.
7 * Within this space are functional units such as the SIU, memory
8 * controller, system timers, and other control functions. It is
9 * a combination that I found difficult to separate into logical
10 * functional files.....but anyone else is welcome to try. -- Dan
