  I would say yes, I'd prefer that defconfigs define BR2_GLOBAL_PATCH_DIR 
to point to board/xxx/yyy/patches. Then they come much closer to how you 
would use buildroot in practice.

  Here also I'm in favour of deprecating them.

  But probably it's better to start using the global patch dir now, and 
only start deprecating the old ways next year.
