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.
+Use the splash_source.c library. 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.
+splashsource 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.
