* sector SA3 is obscured by the 32 kB serial/TOD access space, and
* the 64 kB sectors SA19-SA26 are obscured by the 512 kB PLCC
* containing the fixed boot ROM. (If the 512 kB PLCC is
* deconfigured by jumper, this window to Flash Bank 0 becomes
* visible, but it still contains the fixed boot code and should be
* considered read-only). Flash Bank 0 sectors SA0 (16 kB), SA1 (8
* kB), and SA2 (8 kB) are currently unused.
*
* 2 MB Flash Bank 1 runs in 16-bit mode. Flash Bank 1 is fully
* usable, but it's a 16-bit wide device on a 64-bit bus. Therefore
* 16-bit words only exist at addresses that are multiples of 8. All
* PROM data and control addresses must be multiplied by 8.
*
* See flashMap.c for description of flash filesystem layout.
