huge hacks to kinda/sorta work on top of android fbdev + downstream
gpu driver, so people have some approximate chance of getting
freedreno/x11 working on $random_android_device.. see:
mostly it is to try to (best-effort) support devices with dsi panels,
since it was only recently that upstream drm/kms driver grew decent
dsi support. I'm planning to write panel drivers for a handful of
devices, to give reasonable example for anyone with
$random_android_device to start with, so between that and the fact
that fbdev support barely works (due to differences between different
devices) I'll probably torpedo the fbdev support eventually..
