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.
