+ * 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
