+ * MPC8xx Communication Processor Module.
+ * Copyright (c) 1997 Dan Malek (dmalek@jlc.net)
+ *
+ * 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.
