Milk-V Mars single board computer features RISC-V StarFive processor

So now we are up to three SBCs plus the PineTab-V using the JH7110 SoC, which is kind of somewhere between Pi 3 and Pi 4 as long as you don't need SIMD. Closer to Pi 4 because while the CPU is a little weaker the Pi 3 has never had more than 1 GB RAM, and both Pis have got worse I/O, including GPU.

I think pretty soon there will be multiple TH1520 boards too, which definitely beat Pi 4 in all respects, including SVE/RVV-class vector processing.

Both chips are a little short on drivers right now, but that will change within a few months.
