   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.
