Well, my plan was to get at least minimum bits mainlined and then build
additional features on top.
Wens, it would be cool though, if you could share your plans.
Unfortunately I have only single A10 device (with LVDS and mini-HDMI)
but I don't actually have other LVDS-displays I could easily use with
A20 devices (I have CubieTruck and A20-Olinuxino Micro).
