Add Kconfigs which enable the video driver and splash screen at SPL stage only and not at u-boot proper. The existing Kconfigs from u-boot proper were not used to make SPL splash screen independent to them.

+config SPL_VIDEO + bool "Enable driver model support for LCD/video" + depends on SPL_DM + help + The video subsystem adds a small amount of overhead to the image. + If this is acceptable and you have a need to use video drivers in + SPL, enable this option.

It appears at the top right. The logo itself is at + tools/logos/u-boot_logo.bmp and looks best when the display has a + black background. + +config SPL_SPLASH_SCREEN + bool "Show a splash-screen image at SPL" + help + If this option is set, the environment is checked for a variable + "splashimage" at spl stage. + +config SPL_SYS_WHITE_ON_BLACK + bool "Display console as white on a black background at SPL" + help + Normally the display is black on a white background, Enable this + option to invert this, i.e. white on a black background at spl stage. + This can be better in low-light situations or to reduce eye strain in + some cases. + +config SPL_VIDEO_PCI_DEFAULT_FB_SIZE + hex "Default framebuffer size to use if no drivers request it at SPL" + 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 SPL_CONSOLE_SCROLL_LINES + int "Number of lines to scroll the console by at SPL" + default 1 + help + When the console need to be scrolled, this is the number of + lines to scroll by.

This library provides facilities to + declare board specific splash image locations, routines for loading + splash image from supported locations, and a way of controlling the + selected splash location using the "splashsource" environment + variable. + + This CONFIG works as follows: + + - If splashsource is set to a supported location name as defined by + board code, use that splash location. + - If splashsource is undefined, use the first splash location as + default. + - If splashsource is set to an unsupported value, do not load a splash + screen. + + A splash source location can describe either storage with raw data, a + storage formatted with a file system or a FIT image. In case of a + filesystem, the splash screen data is loaded as a file. The name of + the splash screen file can be controlled with the environment variable + "splashfile". + + To enable loading the splash image from a FIT image, CONFIG_FIT must + be enabled. The FIT image has to start at the 'offset' field address + in the selected splash location.
