Was this tested with SPL support? I don't see DRAM configuration here
so it seems that it relies on the non-free rockchip loader.

If that is the case, could you please indicate that in the commit
message?

To maintainers: please do not merge this series before DRAM init and
SPL support is available for these boards.

It seems that other RK3399 boards were merged without SPL support and
sofar, I have the feeling that nobody cared to explain how we got into
this broken situation. Please don't merge any more such board.

Cheers,

Paul
