   8 U-Boot MPC8xx video controller driver
   9 ======================================
  10
  11 The driver has been tested with the following configurations:
  12
  13 - MPC823FADS with AD7176 on a PAL TV (YCbYCr)   - arsenio@tin.it
  14 - GENIETV    with AD7177 on a PAL TV (YCbYCr)   - arsenio@tin.it

  17 "video-mode" environment variable
  18 ===============================
  19
  20 The 'video-mode' environment variable can be used to enable and configure
  21 some video drivers.  The format matches the video= command-line option used
  22 for Linux:
  23
  24         video-mode=<driver>:<xres>x<yres>-<depth>@<freq><,option=string>
  25
  26         <driver>        The video driver name, ignored by U-Boot
  27         <xres>          The X resolution (in pixels) to use.
  28         <yres>          The Y resolution (in pixels) to use.
  29         <depth>         The color depth (in bits) to use.
  30         <freq>          The frequency (in Hz) to use.
  31         <options>       A comma-separated list of device-specific options
  32
  33 Example: video-mode=fslfb:1280x1024-32@60,monitor=dvi
