Significant parts of coreboot are GPLv2-only. Deliberately so.
Under the continental European legal tradition, any statement pointing to the GPLv2(+) should be good enough. Unfortunately there are those letter-over-spirit jurisdictions that didn't get to enjoy Napoleon modernizing their legal code (but then, they didn't have to endure the rest, either). (All IANAL)
