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