3 * MPC8xx Internal Memory Map
4 * Copyright (c) 1997 Dan Malek (dmalek@jlc.net)
5 *
6 * The I/O on the MPC860 is comprised of blocks of special registers
7 * and the dual port ram for the Communication Processor Module.
8 * Within this space are functional units such as the SIU, memory
9 * controller, system timers, and other control functions. It is
10 * a combination that I found difficult to separate into logical
11 * functional files.....but anyone else is welcome to try. -- Dan
