Which is the advantage instead of using the "preboot" variable setting CONFIG_PREBOOT ? It does pretty the same and you can move the whole script outside of board code.
The preboot command is run too late. It looks like it is run in main_loop but U-Boot looks for the splash image at the address in the splashimage variable in board_init_r -> stdio_init -> drv_lcd_init or drv_video_init (depending on whether you have CONFIG_LCD or CONFIG_VIDEO).
You are describing a bug - then it should be fixed globally, not only for this board.
What's the bug? - preboot being called too late, or - splash_screen_prepare() being called too early
It seems that having splash_screen_prepare() called early makes sense, because stdout could be set to include VGA and having access to stdout is very useful in preboot commands.
Please advise,
Eric
