I tried the really hard way with a RK3288 (Asus TinkerBoard). After about a month I had a barely working uboot built from unpatched official sources. After two months I still didn't have a bootable kernel built from unpatched official sources. - with power regulator drivers, the board powers itself off while booting - without power regulator drivers, it boots the kernel, but there's no power to usb, ethernet and wifi. What I learned: To stay away from Rockchip.
