Ok, we're starting the process of creating a 'real' RISC-V semihosting
spec. This references the existing 2.0 version of the ARM semihosting
specification, defining only the RISC-V specific details necessary.
I've created a public github repository containing this work; that is
likely to eventually move over to the RISC-V github repository.


The goal is to enable RISC-V semihosting implementations that share most
of the underlying details with existing ARM semihosting implemenations.
