- help
- This enables support for integrated graphics on Intel ivybridge
- devices. Initialisation is mostly performed by a VGA boot ROM, with
- some setup handled by U-Boot itself. The graphics adaptor works as
- a VESA device and supports LCD panels, eDP and LVDS outputs.
- Configuration of most aspects of device operation is performed using
- a special tool which configures the VGA ROM, but the graphics
- resolution can be selected in U-Boot.

- (USB Keyboard, AT Keyboard).
- config VIDEO_SW_CURSOR
- bool "Enable a software cursor"
- depends on CFB_CONSOLE
- default y if CFB_CONSOLE

- position when entering text on the console. It is recommended to
- enable this.
- config CONSOLE_EXTRA_INFO
- bool "Display additional board information"
