PS6: 
Just one Kconfig nit and OC questions... looks quite good otherwise :)

PS6, Line 4: 	def_bool n
Technically, a `def_bool n` isn't necessary. Only difference are
not being able to override the default later and .config cosmetics:
without a default it won't show up as not enabled. For a mainboard
option, I'd prefer to remove it, i.e. just have `bool` here (other-
wise it would be mentioned in every coreboot .config, no matter
what board is selected).

PS6, Line 7: OC_SKIP
No OC pin seems unlikely for a laptop's external ports. Was this confirmed? or is it simply unknown?
