Subject: [PATCH 11/12] pcm043: enable l2x0 cache
Date: Tue, 30 Mar 2010 13:06:54 +0200	[thread overview]
Message-ID: <1269947215-18214-12-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1269947215-18214-1-git-send-email-s.hauer@pengutronix.de>

Also, initialize the MMU in a postcore_initcall to enable
it earlier.
