I'm running a BBB with a very recent image (details below) with an HDMI 
touchscreen connected. Everything is setup and working very well, but 
between the kernel, OS, and Application startup there's a solid minute 
before anything appears on the screen. I'm looking into optimizing this at 
a later date, but in the meantime I'm searching around to see if anyone has 
successfully gotten U-Boot to throw a splash image over the HDMI output 
without much luck. I've successfully bitbanged the GPIO via UBoot to do 
something similar on a two line LCD display, and see a ton of info on doing 
this with a normal LCD screen, but haven't seen much as far as actual HDMI.

I grabbed the latest U-Boot and successfully built it from source in the 
event I need to actually hack it apart to get it to work, *but I'm just 
looking for any guidance on where to start with that process, or if anyone 
has actually successfully done it*?
