FireMarshal for Prototype Platform

[abejgonzalez]

This is the initial work to get FireMarshal working for the prototype platform (specifically the VCU118). This adds a new "board" called prototype and a new "simple" configuration called br-chip-base.json.

This works with GPIOs, SDCard.

TODO:

• Add install functionality to run the change-addresses on the output of the build
• Clean up the Linux and Busybox configs more
• Fix the modprobe failing since there are no Linux modules on the prototype (fails in the init script when loading FireMarshal modules and in the default init script)
• Expect FireMarshal test output (from ./scripts/fullTest.py)

This looks good to me in general, just some minor comments.

I'll trust you to have tested it sufficiently. Have you run firemarshal/scripts/fullTest.py with the different board configured? I suppose it should work but it's worth checking.

I think most of it should work... but I'm not sure if you have tests that need the block/NIC modules. I'll do more thorough testing before it gets merged.

I think there are one or two tests that rely on the drivers. The test script will run all tests and report which ones failed so we can double check that it's only those that we expect to fail.

As an FYI, Im getting alot of failures running the regressions suite that seem to point to BWRC issues rather than issues with the workload. I've gone ahead and tested the following on the VCU118 prototype platform:

./marshal -v -d build br-base.json with BBL and OpenSBI
and
./marshal -v -d install -t prototype br-base.json

I'll run the test suite on an EC2 machine later to see if I can get things to work better.

[abejgonzalez]

I don't think running the test suite is good right now mainly because the prototype platform doesn't include bash which nullifies most if not all of the tests (things hang since the scripts can't be run). I fixed some other small issues but this should be good to go now if you don't mind running the test suite fully.

lgtm. All tests passed on firechip board.
