Is it appropriate to include third-party code that is not under the Apache 2.0 license in a submission? The relevant FAQ entry is not super direct about this: <https://efabless.com/open_mpw_faq>

Yes, but you need to format it like this:
third_party/something/LICENSE
third_party/something/...files...

Your top level Makefile and wire glue needs to be Apache 2

Also obviously license needs to be compatible with Apache 2 ...

And you should probably do some kind of patent due diligence on the full combined system, since patents are the reason to use Apache 2

You save a lot of people time on not having to check your Apache2 dependencies for patents!!

Note, IANAL, IANYL, this should not be interpreted as individualized legal advice

Although ... Apache 2 only grants license to patents of the author ... doesn't say anything about patents held by other people.
