/*
 *
 * FILE : MPC5604P_HWInit.h
 *
 * DESCRIPTION:
 *  This file contains all MPC5604P derivative needed initializations, 
 *  and all initializations for the MPC5604P boards which are supported.
 *  This includes setting up the External Bus Interface to allow access to 
 *  memory on the external bus, and ensuring there is a valid entry in the
 *  MMU for the external memory access.
