| 17 | * This is the CPU physical memory map (windows must be at least 1MB and start |
| 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 |
| 23 | * |
| 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 |
