Do you have a copyright assignment with the FSF? If not and you don't want to do this, then I can try to add the RISCV support to GCC without locking at your GCC patches. We should commit the things first into GCC.

Are there plans by the RISCV people to add this to upstream Newlib soon? Due to the RISCV support in FSF Binutils and GCC, there should be no problems.
