This patch enables flash protection(lock/unlock) for CFI devices. This is necessary because the Parallel NOR flash connected on the spear boards, M28W64, can be locked/unlocked on a sector basis. Moreover, all its sectors are in locked state at reset and these have to be unlocked explicitly before being erased or written.
