RISC-V is an interesting, relatively new and open source hardware platform. The inventors of RISC-V created a company called HiFive and that company recently released a desktop-class System on a Chip (SoC) board called HiFive Unmatched. Long before this release Haiku developer Alexander von Gluck (kallisti5) had pre-ordered this board and had begun work on the Haiku port to RISC-V, making some progress on the boot loader, u-boot support and memory mapping.
More hardware is needed to build a complete computer with the HiFive Unmatched so I am sure X512 would appreciate some help there. He has told me that once he gets the board next week he will start a new forum thread to track his progress.
