Wolfgang,
I know you are favouring a migration of U-Boot to GPLv3, but currently it is still licensed under v2 (although most code is v2 'or later')
I have some v3 code I would like to bring in (from GRUB). Will that cause any issues?
Regards,
Graeme

It is my understanding that you cannot "downgrade" GPLv3 code, i. e. you cannot link it into a GPLv2 project. But then, I'm not a license expert, and IANAL.
Best regards,

in-my-not-a-lawyer-opinion, i think introducing GPLv3 code makes the final output GPLv3 only if the build includes it.
so if the imported GRUB code stays at GPLv3, and is only for x86, and all of the code Graeme is using from u-boot is GPLv2+, then the final result there is under GPLv3 only. but all his GPLv3 code, assuming it's specific to x86, wont affect other architectures. -mike

I guess this is correct.

But Graeme would also have to make sure not topick up any partsof the U-Boot code that are GPLv2 (without the "or later" phrase). A license nightmare...

Wolfgang Denk

I plan on doing a complete GPLv3 audit to see if we can create a usable U-Boot build which is 100% GPLv3 compatible
