| 2 | Splash Screen |
| 3 | --------------------------------------------------------------------- |
| 4 | The splash_screen_prepare() function is a weak function defined in |
| 5 | common/splash.c. It is called as part of the splash screen display |
| 6 | sequence. It gives the board an opportunity to prepare the splash |
| 7 | image data before it is processed and sent to the frame buffer by |
| 8 | U-Boot. Define your own version to use this feature. |

| 10 | CONFIG_SPLASH_SOURCE |
| 11 | |
| 12 | Use the splash_source.c library. This library provides facilities to declare |
| 13 | board specific splash image locations, routines for loading splash image from |
| 14 | supported locations, and a way of controlling the selected splash location |
| 15 | using the "splashsource" environment variable. |
| 16 | |
| 17 | splashsource 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. |
