Thanks for the info. I will have to start with the picorv32 (RV32IM) or Rocket Chip itself and see what will fit on my Papilio board. If I wanted to hack on RTL and a toolchain, is the GCC port or LLVM port easier to start with? There seem to be a couple of LLVM ports... I will go with LLVM-RISCV with RocketChip. Also, any plans of an async RISC-V implementation?

The gcc port is mature and has been upstreamed. The LLVM port is still a work-in-progress. I know there's been at least one talk presenting some thesis work on an clock-less RISC-V design at an early RISC-V workshop, but I'm not aware of any in-progress implementations.
