| 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". |
