From 157af4f81fffd416d8952cd9ca5c5decc6d6de9e Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Sun, 3 Dec 2017 06:24:53 -0600 Subject: [PATCH] ARM: omap3_logic: Unlock NAND automatically in U-Boot The Micron Flash is locked by default. This will automaticlly unlock so manually unlocking is unnecessary in U-Boot.
