Subject: [PATCH 4/5] S3C2440/NAND: Re-enable the controller after NAND boot test
Date: Sun,  6 Mar 2011 22:53:17 +0100	[thread overview]
Message-ID: <1299448398-5672-5-git-send-email-jbe@pengutronix.de> (raw)
In-Reply-To: <1299448398-5672-1-git-send-email-jbe@pengutronix.de>

From: Juergen Beisert <juergen@kreuzholzen.de>

After running the 'nand_boot_test' command, any usage of the NAND fails with
an IO error. This happens due to the load routine disables the NAND controller
after loading the image.

This patch re-enables the NAND controller again after running the test.
