* 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
|
