Patch Set 3: Code-Review-2

Patchset:

PS2:
> also added CB:75554 , it is already approved.

It is approved in coreboot code review, but not merged in coreboot (unresolved comments). This would make our code of conduct more strict than the code of conduct of coreboot.

It would even make our code of conduct one of the strictest codes of conduct out there. Quick googling didn't find any similar clauses on other FOSS projects.

To quote that clause: "Threatening or starting legal action against the project, sibling projects hosted on coreboot.org infrastructure, project or infrastructure
maintainers leads to an immediate ban from coreboot.org and related
systems."
