CONFIG_SPLASH_SCREEN_PREPARE
If this option is set then the board_splash_screen_prepare()
function, which must be defined in your code, is called as part
of the splash screen display sequence. It gives the board an
opportunity to prepare the splash image data before it is
processed and sent to the frame buffer by U-Boot.
- Gzip compressed BMP image support: CONFIG_VIDEO_BMP_GZIP
If this option is set, additionally to standard BMP

The splash_screen_prepare() function is a weak function defined in
common/splash.c. It is called as part of the splash screen display
sequence. It gives the board an opportunity to prepare the splash
image data before it is processed and sent to the frame buffer by
U-Boot. Define your own version to use this feature.
