[PATCH 04/12] gma500: introduce the framebuffer support code

From: Alan Cox We support 2D acceleration on some devices but we try and do tricks with the GTT as a starting point as this is far faster. The GTT logic could be improved further but for most display sizes it already makes a pretty good decision. Signed-off-by: Alan Cox --- drivers/gpu/drm/gm
