[flashrom] What's the intended license for flashrom?

[Nico Huber]

Hi folks,

I've just noticed that most of flashrom is licensed under GPLv2 + any
later version, while about a third of the code base is GPLv2 only.
I wonder if that is intentional, or if any of the license headers was
just copy pasted and spread too much?

Does somebody know any previous discussion on the topic?

Nico
