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 | |
