@RedTechEngineer @sun I'd more go for the VisionFive 2 from StarFive given their documented Upstream Plan: https://rvspace.org/en/project/JH7110_Upstream_Plan

The last thing I'd want is being stuck to a vendor tree for u-boot and kernel, and I've yet to see anything similar from any other riscv manufacturer.
(ARM gave me enough pains that I tend to assume it's stuck to vendor trees when not documented)
