Yeah, actually Kyle's note (http://lkml.org/lkml/2011/8/29/289) makes
much more sense for linux and the whole firmware in the kernel deal.
So it looks like the drivers should be taught to wait for userspace to
appear instead of Kconfig helping them build-in firmware. And then we
should go ahead and remove CONFIG_EXTRA_FIRMWARE completely...

Thanks.
