- 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.

- hex "Default framebuffer size to use if no drivers request it"
- depends on DM_VIDEO
- default 0x1000000 if X86 && PCI
- default 0 if !(X86 && PCI)
- help
- Generally, video drivers request the amount of memory they need for
- the frame buffer when they are bound, by setting the size field in
- struct video_uc_plat. That memory is then reserved for use after
- relocation. But PCI drivers cannot be bound before relocation unless
- they are mentioned in the devicetree.
- With this value set appropriately, it is possible for PCI video
- devices to have a framebuffer allocated by U-Boot.
- Note: the framebuffer needs to be large enough to store all pixels at
- maximum resolution. For example, at 1920 x 1200 with 32 bits per
- pixel, 2560 * 1600 * 32 / 8 = 0xfa0000 bytes are needed.
- config VIDEO_COPY
- bool "Enable copying the frame buffer to a hardware copy"
- depends on DM_VIDEO
- help
- On some machines (e.g. x86), reading from the frame buffer is very
- slow because it is uncached. To improve performance, this feature
- allows the frame buffer to be kept in cached memory (allocated by
- U-Boot) and then copied to the hardware frame-buffer as needed.
- To use this, your video driver must set @copy_base in
- struct video_uc_plat.

- 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"

- 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 SYS_WHITE_ON_BLACK
- bool "Display console as white on a black background"
- default y if ARCH_AT91 || ARCH_EXYNOS || ARCH_ROCKCHIP || ARCH_TEGRA || X86 || ARCH_SUNXI

- Normally the display is black on a white background, Enable this
- option to invert this, i.e. white on a black background. This can be
- better in low-light situations or to reduce eye strain in some
- cases.
- config NO_FB_CLEAR

- If firmware (whatever loads u-boot) has already put a splash image
- on screen, you might want to preserve it until whatever u-boot
