What exactly does HAVE_INIT_TIMER configure? Why do those three boards
_not_ set it? It sounds like all boards would want to set it?

Are all Kconfig files setting to y (via "select" preferrably) where needed?

Why is this removed?

Hm, indeed. Why was this added? Are there situations where we might not
want LOW_TABLES on?

Why this? "select HT3_SUPPORT" should work just fine, no?
Even if that's not the case I think it would be nicer to set it in some
global Kconfig file so we can "select" it. IMHO _all_ y variables should
be "select"ed so we avoid the 4-line chunks...

Ditto.

Why are these three defined twice?

Please drop this hunk, I have a patch in the queue to redo DEBUG_SMBUS
and other DEBUG options globally anyway.

should suffice, I think.
