- Splash Screen
- ---------------------------------------------------------------------
- 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.
- CONFIG_SPLASH_SOURCE
- 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.
- A splash source location can describe either storage with raw data, or storage
- formatted with a file system. 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".
