| * 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 |
