Benchmarking tools for Keystone modifications.
Partially functional, rv8 tests should be fine.
You will need to have a complete build of the rv8 musl toolchain somewhere on your PATH!
Then, KEYSTONE_DIR=PATH_TO_KEYSTONE_ROOT_DIR make, copy the entire
staging/ directory into your keystone's build/overlay/root/,
rebuild the keystone image, and run run_all_tests.sh after booting
and inserting the module.
You will need to copy the logs directory out when done, it will not persist by default in our images.
