The NOR flash device on the SAMA5D3x CPU modules supports hardware sector
protection and according to the flash datasheet: "All blocks power-up in a
locked state to protect array data from being altered during power
transitions".  In order to make your patch set work:

#define CONFIG_SYS_FLASH_PROTECTION

needs adding into the include/configs/sama5d3xek.h file.

Andy.
