> between vrfb and sdram buffers
>
> Add "rotation_type" member to omapvideo_info, this is initialized based on
> the value "def_vrfb" bootarg parameter, vrfb rotation is chosen by
> default.
> The rotation_type var is now used to choose between vrfb and non-vrfb
> calls.
>
> vrfb specific code in omap_vout has been removed and is present in
> omap_vout_vrfb.c
