A thought I had after reading over 8/9 in the series was, could we try
something like:
- In C, loop over everything in w1 and set environment variables based
  on each thing we find.
- In a CONFIG_PREBOOT load a U-Boot shell script in that will look for
  the right env variables to be set for a given DIP and then do whatever
  is needed to load in the overlay.

Does that make sense?
