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).
