2 bool "Enable VESA video driver support"
5 Turn on this option to enable a very simple driver which uses vesa
6 to discover the video mode and then provides a frame buffer for use
7 by U-Boot. This can in principle be used with any platform that

163 anything in the 8MHz-30MHz range and the exact value should be
164 retrieved from the board schematics. Or in the case of Allwinner
165 hardware, it can be usually found as 'lcd_xtal_freq' variable in
166 FEX files. It can be also set to 0 for selecting PCLK from the
167 parallel LCD interface instead of TX_CLK as the PLL clock source.
