Hi!
I'm very glad to see RISC-V support improvement!
Can you please push your RISC-V working branch to github (or other public git repo),
so I can test it too?
At the moment I have at least two out-of tree RISC-V branches that which I want
to rebase on latest barebox with your patches:
* https://github.com/frantony/barebox/tree/20200222.riscv-sifive
contains hacky 64-bit support and add Sifive U500 qemu support.
* https://github.com/litex-hub/barebox/tree/20200727.litex-vexriscv-linux
contains litex SoC with RISC-V 32-bit CPU core support.
It can run linux on Arty, please see
https://github.com/enjoy-digital/litex/issues/413#issuecomment-609047340
It seems, that ethernet driver needs update: https://github.com/litex-hub/barebox/issues/1
I suppose that you can add 'bootm: add RISC-V image type' patch to your series
(I'll send you the patch in a few minutes). The patch used in the litex series.
