Hi all, this patch series introduces a very simple driver for the ARM HDLCD Controller, that means that we can finally have something on the screen while Xen is booting on ARM :) The driver is very limited at the moment and it is only capable of setting one resolution that is 1280x1024. Also it requires the OSC5 timer to be set to 108Mhz in the Versatile Express config file. In order to reduce code duplication with x86, I tried to generalize the existing vesa character rendering functions into a architecture agnostic framebuffer driver that can be used by vesa and the hdlcd drivers. I would very much appreciate if you could give a close look at the vesa changes because I don't have any x86 test machines that boot in vesa mode, therefore I couldn't test it.
