+From e3a91813a659447bd20de014902fc5b1d95272aa Mon Sep 17 00:00:00 2001
+From: Graeme Gregory <gg@a10082.wolfsonmicro.main>
+Date: Mon, 26 Mar 2007 15:47:09 +0100
+Subject: [PATCH] Add smdk2443 s3c2443-ac97 and wm9710 support
+
+This is the machine driver for smdk2443 with wm9710
+
+Also the s3c2443-ac97 driver for use with the above machine driver.
