I always thought every manually created file in the repository should
have license (header). I think that such a rule is not necessarily
required but I am not a lawyer. The GPL notes [1] advise to do, but as
written it seems not to be legally necessary [2].

So could you (Ron, Stefan?) please clarify what to do in coreboot’s
case?

Thanks,

Paul
