Image format
This design configures the framebuffer in Linux simple framebuffer format a8r8g8b8, screen size 1280x720. Images can be converted to this format with ImageMagick.
convert splashscreen.jpg splashscreen.rgba
File extension should be changed to bin, then the file can be added to boot.bin as data file setting load offset to 0x38000000. FSBL would then preload the splash-screen image into framebuffer.
