arm/imx21: Framebuffer support for i.MX21
This patch mimicks what Martin wrote on the mailing list: * move arch/arm/mach-imx/include/mach/imxfb.h into arch/arm/mach-mxc/include/mach/imxfb.h * changes Kconfig so that CONFIG_FB_IMX is selectable * adds a platform device (copied from some pengutronix patches) Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
