 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_BPP8
 	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
 	  this option, such displays will not be supported and console output
 	  will be empty.

 config VIDEO_BPP16
 	bool "Support 16-bit-per-pixel displays"
 	depends on DM_VIDEO
 	default y if DM_VIDEO
 	help
 	  Support drawing text and bitmaps onto a 16-bit-per-pixel display.
 	  Enabling this will include code to support this display. Without
 	  this option, such displays will not be supported and console output
 	  will be empty.

 config VIDEO_BPP32
 	bool "Support 32-bit-per-pixel displays"
 	depends on DM_VIDEO
 	default y if DM_VIDEO
 	help
 	  Support drawing text and bitmaps onto a 32-bit-per-pixel display.
 	  Enabling this will include code to support this display. Without
 	  this option, such displays will not be supported and console output
 	  will be empty.

 config CONSOLE_NORMAL
 	bool "Support a simple text console"
 	depends on DM_VIDEO
 	default y if DM_VIDEO
 	help
 	  Support drawing text on the frame buffer console so that it can be
 	  used as a console. Rotation is not supported by this driver (see
 	  CONFIG_CONSOLE_ROTATION for that). A built-in 8x16 font is used
 	  for the display.

 config CONSOLE_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 CONSOLE_TRUETYPE
 	bool "Support a console that uses TrueType fonts"
 	depends on DM_VIDEO
 	help
 	  TrueTrype fonts can provide outline-drawing capability rather than
 	  needing to provide a bitmap for each font and size that is needed.
 	  With this option you can adjust the text size and use a variety of
 	  fonts. Note that this is noticeably slower than with normal console.

 config CONSOLE_TRUETYPE_SIZE
 	int "TrueType font size"
 	depends on CONSOLE_TRUETYPE
 	default 18
 	help
 	  This sets the font size for the console. The size is measured in
 	  pixels and is the nominal height of a character. Note that fonts
 	  are commonly measured in 'points', being 1/72 inch (about 3.52mm).
 	  However that measurement depends on the size of your display and
 	  there is no standard display density. At present there is not a
 	  method to select the display's physical size, which would allow
 	  U-Boot to calculate the correct font size.

 config VIDCONSOLE_AS_LCD
 	bool "Use 'vidconsole' when 'lcd' is seen in stdout"
 	depends on DM_VIDEO
 	help
 	  This is a work-around for boards which have 'lcd' in their stdout
 	  environment variable, but have moved to use driver model for video.
 	  In this case the console will no-longer work. While it is possible
 	  to update the environment, the breakage may be confusing for users.
 	  This option will be removed around the end of 2016.

 config VIDEO_COREBOOT
 	bool "Enable coreboot framebuffer driver support"
 	depends on X86 && SYS_COREBOOT
 	help
 	  Turn on this option to enable a framebuffer driver when U-Boot is
 	  loaded by coreboot where the graphics device is configured by
 	  coreboot already. This can in principle be used with any platform
 	  that coreboot supports.

 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).

	This sets the font size for the console. The size is measured in
	pixels and is the nominal height of a character. Note that fonts
	are commonly measured in 'points', being 1/72 inch (about 3.52mm).
	However that measurement depends on the size of your display and
	there is no standard display density. At present there is not a
