Check out the SAT solver link I quoted in the prior email.. That sounds like a really interesting solution. The defconfigs would ultimately hold just what's unique to a given board, then the solver would figure out what to else to enable just from those unique properties.
So we would still have defconfigs , but they would not have loads of duplication like they do now.
I don't see how we can do without defconfigs altogether tho. I mean , if you want to run a Beagle board or a Nexus one we can't just give the users a slim ARM config and let them troll through 1000's of drivers trying to find just those ones that work on their given board.
