One place: yes (Kconfig files, for example).
Parts of the settings will be generic, others may be mainboard-specific.
But we can still make Kconfig stick them all in the same menu (from a
user-perspective) is we want, so that's not a problem.

Set a default at compile time, but allow overriding via CMOS settings.
Not sure what exactly inheriting and per-component options mean here.

Yes. AFAICS Kconfig can handle everything we have in cmos.layout files
now: numbers, strings, multiple-selects (with a default value), etc. etc.

Hm, yes, probably. Needs some more investigations, maybe.
