| 6 | Turn on this option to enable a very simple driver which uses vesa |
| 7 | to discover the video mode and then provides a frame buffer for use |
| 8 | by U-Boot. This can in principle be used with any platform that |
| 9 | supports PCI and video cards that support VESA BIOS Extension (VBE). |
