From 187ef15268e638603dea55a91fdfa29feaed6d13 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?H=C3=A5vard=20Skinnemoen?= Date: Fri, 22 Sep 2006 10:07:08 +0100 Subject: [MTD] Unlock NOR flash automatically where necessary MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce the MTD_STUPID_LOCK flag which indicates that the flash chip is always locked after power-up, so all sectors need to be unlocked before it is usable. If this flag is set, and the chip provides an unlock() operation, mtd_add_device will unlock the whole MTD device if it's writeable. This means that non-writeable partitions will stay locked. Set MTD_STUPID_LOCK in fixup_use_atmel_lock() so that these chips will work as expected.
