Added (minimal) comments for  in Kconfig, so that
configurators can choose this entry explicitly.

A more descriptive comment by someone else is appreciated...

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
