8 bool "Enable driver model support for LCD/video"
11 This enables driver model for LCD and video devices. These support
12 a bitmap display of various sizes and depths which can be drawn on
13 to display a command-line console or splash screen. Enabling this
14 option compiles in the video uclass and routes all LCD/video access
18 bool "Support 8-bit-per-pixel displays"
22 Support drawing text and bitmaps onto a 8-bit-per-pixel display.
23 Enabling this will include code to support this display. Without
24 this option, such displays will not be supported and console output
28 bool "Support 16-bit-per-pixel displays"
32 Support drawing text and bitmaps onto a 16-bit-per-pixel display.
33 Enabling this will include code to support this display. Without
34 this option, such displays will not be supported and console output
38 bool "Support 32-bit-per-pixel displays"
42 Support drawing text and bitmaps onto a 32-bit-per-pixel display.
43 Enabling this will include code to support this display. Without
44 this option, such displays will not be supported and console output
48 bool "Support rotated displays"
51 Sometimes, for example if the display is mounted in portrait
52 mode or even if it's mounted landscape but rotated by 180degree,
53 we need to rotate our content of the display relative to the
54 framebuffer, so that user can read the messages which are
55 printed out. Enable this option to include a text driver which can
56 support this. The rotation is set by the 'rot' parameter in
57 struct video_priv: 0=unrotated, 1=90 degrees clockwise, 2=180
58 degrees, 3=270 degrees.
61 bool "Enable VESA video driver support"
64 Turn on this option to enable a very simple driver which uses vesa
65 to discover the video mode and then provides a frame buffer for use
66 by U-Boot. This can in principle be used with any platform that
67 supports PCI and video cards that support VESA BIOS Extension (VBE).
