U-Boot MPC8xx video controller driver
======================================

The driver has been tested with the following configurations:

- MPC823FADS with AD7176 on a PAL TV (YCbYCr)	- arsenio@tin.it
- GENIETV    with AD7177 on a PAL TV (YCbYCr)	- arsenio@tin.it


"video-mode" environment variable
===============================

The 'video-mode' environment variable can be used to enable and configure
some video drivers.  The format matches the video= command-line option used
for Linux:

	video-mode=<driver>:<xres>x<yres>-<depth>@<freq><,option=string>

	<driver>	The video driver name, ignored by U-Boot
	<xres>		The X resolution (in pixels) to use.
	<yres>		The Y resolution (in pixels) to use.
	<depth>		The color depth (in bits) to use.
	<freq>		The frequency (in Hz) to use.
	<options>	A comma-separated list of device-specific options

Example: video-mode=fslfb:1280x1024-32@60,monitor=dvi
