EARLY_DEBUG was the right idea. Only for some reason it's called EARLY_UART
on rk3288.

I tested rock2 and it is getting dbw parameter of 2 instead of 1 for with
the unmodified code for both channels. I'm afraid I do not know the
significance of this and don't have a good way to test for stability. I am
using rock2 square model a with 2gb ram.
