There are some things to notice
* AT91SAM7S64 is tested
* All AT91SAM7Sxx and AT91SAM7Xxx should work but is not tested
* All parameters are identified from onchip configuartion registers
*
* The flash controller handles erases automatically on a page (128/265 byte) basis
* Only an EraseAll command is supported by the controller
* Partial erases can be implemented in software by writing one 0xFFFFFFFF word to
* some location in every page in the region to be erased
*
* Lock regions (sectors) are 32 or 64 pages
