Move board/compulab/common/splash.c code to common/splash_source.c to make it available for everybody. This move renames cl_splash_screen_prepare() to splash_source_load(), and the compilation of this code is conditional on CONFIG_SPLASH_SOURCE. splash_source features: * Provide a standardized way for declaring board specific splash screen locations * Provide existing routines for auto loading the splash image from the locations as declared by the board * Introduce the "splashsource" environment variable, which makes it possible to select the splash image source. cm-t35 and cm-fx6 are updated to use the modified version.

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.
