Is there anything you could share as a starting point? 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.
