Kamal Dasu 9d2ee0a60b mtd: nand: brcmnand: Check flash #WP pin status before nand erase/program ... On brcmnand controller v6.x and v7.x, the #WP pin is controlled through the NAND_WP bit in CS_SELECT register. The driver currently assumes that toggling the #WP pin is instantaneously enabling/disabling write-protection, but it actually takes some time to propagate the new state to the internal NAND chip logic. This behavior is sometime causing data corruptions when an erase/program operation is executed before write-protection has really been disabled.
