| 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 |
