+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
+
+"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
