  7. U-Boot MPC8xx video controller driver
  8. ======================================
  9. The driver has been tested with the following configurations:
  10. - MPC823FADS with AD7176 on a PAL TV (YCbYCr) - arsenio@tin.it
  11. - GENIETV with AD7177 on a PAL TV (YCbYCr) - arsenio@tin.it
  12. "video-mode" environment variable
  13. ===============================
  14. The 'video-mode' environment variable can be used to enable and configure
  15. some video drivers. The format matches the video= command-line option used
  16. for Linux:
  17. video-mode=<driver>:<xres>x<yres>-<depth>@<freq><,option=string>
  18. <driver> The video driver name, ignored by U-Boot
  19. <xres> The X resolution (in pixels) to use.
  20. <yres> The Y resolution (in pixels) to use.
  21. <depth> The color depth (in bits) to use.
  22. <freq> The frequency (in Hz) to use.
  23. <options> A comma-separated list of device-specific options
  24. Example: video-mode=fslfb:1280x1024-32@60,monitor=dvi
