+ *    the 64 kB sectors SA19-SA26 are obscured by the 512 kB PLCC

+ *    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
