8 * This file contains structures and information for the communication
9 * processor channels. Some CPM control and status is available
10 * throught the MPC8xx internal memory map. See immap.h for details.
11 * This file only contains what I need for the moment, not the total
12 * CPM capabilities. I (or someone else) will add definitions as they
15 * On the MBX board, EPPC-Bug loads CPM microcode into the first 512
16 * bytes of the DP RAM and relocates the I2C parameter area to the
17 * IDMA1 space. The remaining DP RAM is available for buffer descriptors
