You need a servo connector on the board - see here: https://www.chromium.org/chromium-os/servo > 3.

I normally start up U-Boot from scratch, but it sounds like you are chain-loading it. In that case I'm not sure what to do as I have not tried it. Your steps sound correct. I've copied Tomeu who may know how to do this. If you figure it out it would be great to get a patch to README.rockchip.
