An architecture plug-in that allows binary ninja to load RISC-V ELF binaries.
First, you will need an installation of capstone that supports RISC-V. Currently you have to install the next branch, e.g.,:
pip install --user 'git+https://github.com/aquynh/capstone.git@next#subdirectory=bindings/python'
Then drop this repository into your plugins directory manually. Note that you should use it from master if possible, releases are somewhat rare.
