+config DM_VIDEO
+ bool "Enable driver model support for LCD/video"
+ depends on DM
+ help
+ This enables driver model for LCD and video devices. These support
+ a bitmap display of various sizes and depths which can be drawn on
+ to display a command-line console or splash screen. Enabling this
+ option compiles in the video uclass and routes all LCD/video access
+ through this.

+config VIDEO_ROTATION
+ bool "Support rotated displays"
+ depends on DM_VIDEO
+ help
+ Sometimes, for example if the display is mounted in portrait
+ mode or even if it's mounted landscape but rotated by 180degree,
+ we need to rotate our content of the display relative to the
+ framebuffer, so that user can read the messages which are
+ printed out. Enable this option to include a text driver which can
+ support this. The rotation is set by the 'rot' parameter in
+ struct video_priv: 0=unrotated, 1=90 degrees clockwise, 2=180
+ degrees, 3=270 degrees.
