+ * This file contains structures and information for the communication

+ * through the 68360 internal memory map.  See include/asm/360_immap.h for details.
+ * This file is not a complete map of all of the 360 QUICC's capabilities
+ *
+ * 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.
