 * This is the CPU physical memory map (windows must be at least 1MB and start
 * on a boundary that is a multiple of the window size):
 *
 * Seems on the IBM 750FXGX Eval board, the MV64460 Registers can be in
 * only 2 places per switch U17 0x14000000 or 0xf1000000 easily - chose to
 * implement at 0xf1000000 only at this time
 *
 *    0xfff00000-0xffffffff      - 8 Flash
 *    0xffe00000-0xffefffff      - BOOT SRAM
 *    0xffd00000-0xffd00004      - CPLD
 *    0xffc00000-0xffc0000f      - UART
 *    0xffb00000-0xffb07fff      - FRAM
 *    0xff840000-0xffafffff      - *** HOLE ***
 *    0xff800000-0xff83ffff      - MV64460 Integrated SRAM
 *    0xfe000000-0xff8fffff      - *** HOLE ***
