I originally tried to use the CONFIG_SPLASH_SCREEN_PREPARE functionality.
After some frustration, I figured out that without CONFIG_LCD, it is never
actually called.
http://git.denx.de/?p=u-boot/u-boot-imx.git;a=blob;f=common/stdio.c;h=5d5117c0ed838195a2caad7c28c128247771cd92;hb=HEAD#l216

It does seem odd that there are 2 totally different paths and the other
splash screen related macros are used in both but the prepare function is
only called in the LCD case.

Since we use CONFIG_VIDEO and not CONFIG_LCD, this seemed to be the best,
or at least the least invasive, solution.

I apologize for that.  I'm new and didn't know till after I'd already sent
it.  I did CC the board maintainer, Eric.  We also went over the code in
person.
