omap3_dss: add optional framebuffer
The beagle board uses the background color to show an orange screen during startup. This patch adds the ability to add a frame buffer, with the intention not to break the beagle board use case (I don't have one). videomodes.c is not used. Scrolling depends on this patch: http://patchwork.ozlabs.org/patch/155662/ cc: trini@ti.com cc: s-paulraj@ti.com cc: khasim@ti.com Signed-off-by: Jeroen Hofstee <jhofstee@victronenergy.com>
