| 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. | |

| 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. |
