[U-Boot] OMAP3, RFBI, splash screen

Hi, all!

I'm trying to implement splash screen on OMAP35xx-based device with 128x128 1bpp display connected using RFBI, plain parallel interface. Display has controller and own memory, and is controlled with parallel interface, 8-bit wide data bus and signals.

This display works under Linux, but I can't implement that using u-boot, display just doesn't power on, while I see that data is on bus with oscilloscope. Linux version works using interrupts, so I can't do this with u-boot, and that'd be simply overkill using this in u-boot. I think I miss something simple.

Have anybody implemented such a thing, I just need to make it into dumb parallel mode, just to display simple image. Any examples, ideas?

All the best, S.
