Yes, OK. I wasn't talking about this patch in particular at that point, I was more curious whether you agreed that we need to document in some way those vars in `make help` or not. If you see value in documenting them then I can sit down and try to come up with v3 that will (in one way or another) give a simple "help" description for each of Kconfig's vars.
