Recently we have ported a video driver to the MPC823 using the video
encoder AD7176. The problem is, that the pixels data in the framebuffer
must have the YUV or Y-Cb-Y-Cr-Format which is rarely used, at least I
have not found any support in Linux or Microwindows. You can find the
port on our linux-2.4 CVS tree (see http://www.denx.de/re/linux.html).
Check for "arch/ppc_8xx/video823.c" and "drivers/video/fbcon-yuv.c".
Hope it helps,
Wolfgang.
