I don't own this OpenIP video hardware and I didn't write this code. I
don't work for Phytec or Pengutronix; I'm just a customer.  I needed
some newer features from the current u-boot and I had to port
Pengutronix's release of u-boot 1.2 up to current git head.  I want to
get this code included in u-boot so it won't get stale again.

If you want I can just delete the support for CONFIG_VIDEO_OPENIP.
