There is. And I'll clean it up a bit. The BSP bootstrap
currently has a couple of different steps that are local
to your build (but eventually merge to the kernel tree if
a board is supported) which allow you to work directly in
the kernel git repo for your board work.

In the near future I'll have some updates for BSP
bootstrapping, both code and documents. But I'm more
than happy to walk through this right now if there
is interest.

Cheers,
