Wow, I'm suprised to discover this meta-rockchip :)

Rockchip engineers also publish a meta-rockchip on Github (, although

Those two repos seem quite complementary, Jeffy being focussed on kernel 4.4, and Trevor on mainline.
Wouldn't it make sense to merge all this work in a single place ?

using that for your MACHINE instead of "tinker-board".
