		a multiple of FPROTECT_BLOCK_SIZE and the Factory Data partition to be placed
		right after the application partition in the address space (the Factory Data
		partition offset must be equal to the last address of the application partition).
		The second requirement is valid only when the FPROTECT_BLOCK_SIZE is bigger than
		the flash memory page size.
