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.

	bool "Support 8-bit-per-pixel displays"
	depends on DM_VIDEO
	default y if DM_VIDEO
	help
	  Support drawing text and bitmaps onto a 8-bit-per-pixel display.
	  Enabling this will include code to support this display. Without

	  will be empty.

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.

config VIDEO_VESA
	bool "Enable VESA video driver support"
	default n
	help
	  Turn on this option to enable a very simple driver which uses vesa
	  to discover the video mode and then provides a frame buffer for use
	  by U-Boot. This can in principle be used with any platform that
	  supports PCI and video cards that support VESA BIOS Extension (VBE).

config FRAMEBUFFER_SET_VESA_MODE
