Subject: [PATCH 04/16] add a add_mem_device function
Date: Tue, 19 Jul 2011 18:09:00 +0200	[thread overview]
Message-ID: <1311091752-9114-4-git-send-email-plagnioj@jcrosoft.com> (raw)
In-Reply-To: <20110719160758.GK5727@game.jcrosoft.org>

From: Sascha Hauer <s.hauer@pengutronix.de>

Add a helper function for boards to register their memory
devices. This makes the board code smaller and also helps
getting rid of map_base and struct memory_platform_data.

And switch all of the memory to it
