From 8bf2ce6ea4ee840b70f55a27f80e1cd308051b13 Mon Sep 17 00:00:00 2001 From: Nick Hainke Date: Mon, 27 Dec 2021 00:38:13 +0100 Subject: [PATCH 1/2] mtd: spi-nor: locking support for MX25L6405D Macronix MX25L6405D supports locking with four block-protection bits. Currently, the driver only sets three bits. If the bootloader does not sustain the flash chip in an unlocked state, the flash might be non-writeable. Add the corresponding flag to enable locking support with four bits in the status register. Tested on Nanostation M2 XM.
