Anyone working on up-streaming u-boot for the Clockwork Core R-01? I’d love to improve OS support on the R-01, but lack of upstream u-boot support is kind of a blocker for any kind of work.
I see GitHub - smaeul/u-boot: Patches include sunxi platform support and various driver fixes , but it looks pretty quiet and I don’t see any attempts to upstream the changes.

I would have liked to dive into it, starting from what had been explored here, but I (still) don’t have enough time to devote to it.
Actually i did and i can provide some tips.
Apparently you don’t need UART for this job, at least not in the best case scenario, but to the point.
Your idea with patch for C906’s fence issue was right way to go.
Also @ylyamin ’s resource was a goldmine. Upgrading openSBI isn’t that scary G…
In fact I wanted to shunt u-boot to do baremetal stuff directly after openSBI in place of u-boot.
