7 | * This file contains structures and information for the communication | |
8 | * processor channels. Some CPM control and status is available | |
9 | * through the 68360 internal memory map. See include/asm/360_immap.h for details. | |
10 | * This file is not a complete map of all of the 360 QUICC's capabilities | |
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. | |
