This provides backlight uclass driver that enables basic panel
backlight support.
+config VIDEO_PCI_DEFAULT_FB_SIZE
+ 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_platdata. 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_platdata.
