1--------------------------------------------------------------------- 2Splash Screen 3--------------------------------------------------------------------- 4The splash_screen_prepare() function is a weak function defined in 5common/splash.c. It is called as part of the splash screen display 6sequence. It gives the board an opportunity to prepare the splash 7image data before it is processed and sent to the frame buffer by 8U-Boot. Define your own version to use this feature. 9 10CONFIG_SPLASH_SOURCE 11 12Use the splash_source.c library. This library provides facilities to declare 13board specific splash image locations, routines for loading splash image from 14supported locations, and a way of controlling the selected splash location 15using the "splashsource" environment variable. 16 17splashsource works as follows: 18- If splashsource is set to a supported location name as defined by board code, 19 use that splash location. 20- If splashsource is undefined, use the first splash location as default. 21- If splashsource is set to an unsupported value, do not load a splash screen. 22
