Yeah, it's better not to have Kconfig options like this since it's
easier for the user if we just encode this into options we know they
have to select already.

So for example they pick 8x50 via Kconfig, so we select for them the
right stuff for 8x50 .. Otherwise we have to assume they know what to
select which may not be the case, plus it could be a pain to go
selecting all the related Kconfig options for low level stuff.

If you respin this please re-send it privately just to me.
