The submodule has a link to our fork. It's clear it's forked from
eembc/coremark and it has all copyrights+license details in the
README.

No, not all of them build for RISC-V. I can work on that later.

Looking fine. I ran in QEMU but that won't get sensible numbers. On HW
it depends. For example rv64imafdc it's about 213 iterations per
second on a 50MHz processor (Rocker Chip). I don't have a baseline
(HW+other OSes) for RISC-V to compare against yet.
