Well, it's basically for supporting any v7 core that isn't designed by ARM.
I don't know if any such cores are supported by [mainline] Linux yet, but I'm
sure they'll turn up.

That makes sense. A8 is probably the most popular v7 core at the moment, so
supporting that should be the priority.
Cheers,
