This patch adds a flash driver for the Atmel SAM E70 SoC. The driver has been kept simple by considering that the flash is only composed of 8-KiB blocks. Indeed an area at the beginning of the flash might be erased with a smaller granularity, and the other blocks can also be erased with a higher granularity. It also only handles the global read/write protection, not the 128-KiB lock regions. A write error is returned if a region is locked. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
