5 * The I/O on the MPC860 is comprised of blocks of special registers
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

2 * MPC8xx Communication Processor Module.
3 * Copyright (c) 1997 Dan Malek (dmalek@jlc.net)
4 *
5 * This file contains structures and information for the communication
6 * processor channels. Some CPM control and status is available
7 * throught the MPC8xx internal memory map. See immap.h for details.
8 * This file only contains what I need for the moment, not the total
9 * CPM capabilities. I (or someone else) will add definitions as they
10 * are needed. -- Dan
11 *
12 * On the MBX board, EPPC-Bug loads CPM microcode into the first 512
13 * bytes of the DP RAM and relocates the I2C parameter area to the
14 * IDMA1 space. The remaining DP RAM is available for buffer descriptors
15 * or other use.
