* 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 ***
* 0xfc000000-0xfdffffff - 32bit Flash
* 0xf1010000-0xfbffffff - *** HOLE ***
* 0xf1000000-0xf100ffff - MV64460 Registers
