Subject: [U-Boot] [PATCH] ARM: omap3_logic: Unlock NAND automatically in U-Boot
Date: Sun, 3 Dec 2017 06:24:53 -0600 [thread overview]
Message-ID: <1512303893-24174-1-git-send-email-aford173@gmail.com> (raw)
The Micron Flash is locked by default. This will automaticlly
unlock so manually unlocking is unnecessary in U-Boot.
