Patch from Tony Lindgren This patch syncs the mainline kernel with linux-omap tree. The highlights of the patch are: - Start adding 24xx support by Paul Mundt - Clean-up of cpu detection by Dirk Behme and Tony Lindgren - Add DSP header by Toshihiro Kobayashi - Add support for mtd-xip by Vladimir Barinov - Add various new mux registers - Move OMAP specific serial defines back to serial.h Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
