Certainly OK for the trunk.  Jakub, Richi & Joseph make the rules for
the release branches.


I had a chat with Jakub and I learned as long as there is no branch
freeze or such, every global reviewer can approve such a patch backport.
So may I ask you, would you mind approving this patch for 6.x and 5.x?

Yes.  Approved for 5.x and 6.x.


After fixing a bootstrap comparison failure on 6.x finally committed to 
6.x (244242) and 5.x (244243)


Thanks,
Andreas

Hi all,

the attached patch brings support for the aarch64-*-freebsd* target.

Bootstraped and tested, results on the list. Not that many results due
to board instabilities I lack a cavium ;)

Ok for main? And if yes, how far can I backport? Down to 5.4?

TIA,
Andreas
