OK, for something in common, we have to think about someone using them
with any yocto kernel, not just 3.4.  Since you're saying they work with
3.0, 3.4 and 3.5, I guess there's not too much risk that they'll break
with 3.2.  If that's not the case, you should probably restrict them to
your BSP (but we don't want multiple copies) either.

The best thing would be to move them into the linux-yocto kernel(s) they
have been tested with - that way users know those features work and are
safe to use in their BSPs.
