I think they wouldn't scale very well, and NOTES.foo wouldn't scale much better (there would be lots of little files to provide sufficient granularity, and enormous ifdefs to decide when to include them). Perhaps almost everything could be handled by arch/bus dependencies, at a cost of making it unclear when things are actually configured. Most drivers would be in the central NOTES only and would be automagically not configured if they depend on something that the arch doesn't support.
