From 484e0b05f2dca43a827c950c91b31e151b48a8ef Mon Sep 17 00:00:00 2001 From: Vipin Kumar Date: Mon, 7 May 2012 13:06:54 +0530 Subject: [PATCH] SPEAr: Enable CONFIG_SYS_FLASH_PROTECTION 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.
