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).

25 The frequency of the crystal, which is clocking SSD2828. It may be
26 anything in the 8MHz-30MHz range and the exact value should be
27 retrieved from the board schematics. Or in the case of Allwinner
28 hardware, it can be usually found as 'lcd_xtal_freq' variable in
Siarhei Siamashkadddccd62015-01-19 05:23:35 +020029 FEX files. It can be also set to 0 for selecting PCLK from the
30 parallel LCD interface instead of TX_CLK as the PLL clock source.
