18 * on a boundary that is a multiple of the window size):
20 * Seems on the IBM 750FXGX Eval board, the MV64460 Registers can be in
21 * only 2 places per switch U17 0x14000000 or 0xf1000000 easily - chose to
22 * implement at 0xf1000000 only at this time
24 * 0xfff00000-0xffffffff - 8 Flash
25 * 0xffe00000-0xffefffff - BOOT SRAM
26 * 0xffd00000-0xffd00004 - CPLD
27 * 0xffc00000-0xffc0000f - UART
28 * 0xffb00000-0xffb07fff - FRAM
29 * 0xff840000-0xffafffff - *** HOLE ***
30 * 0xff800000-0xff83ffff - MV64460 Integrated SRAM
31 * 0xfe000000-0xff8fffff - *** HOLE ***
32 * 0xfc000000-0xfdffffff - 32bit Flash
33 * 0xf1010000-0xfbffffff - *** HOLE ***
34 * 0xf1000000-0xf100ffff - MV64460 Registers
