Hey Kevin,

Yes, I have. I will push a branch for you and let you know,
so you can test with some recent U-Boot.

However... this log you have here is not from the CI20 board,
which is JZ4780 SoC, but from some development board
with a Pistachio SoC!

I thought those were dead, but it seems there are
some Pistachio boards around ?
