I'm inclined to agree with you on this point. I believe there is benefit
in masking uncommon hardware configurations such as PC/104 in order to
reduce clutter in the menus, but you are right that "expert" sounds
somewhat of a misnomer for this use case. I considered adding yet
another Kconfig option to mask these options, but since Kconfig code
isn't my forte, I ultimately decided to keep it simple and depend simply
on EXPERT.

The PC104 Kconfig option has been implicitly masked by EXPERT up to this
point, so I thought it best to keep it masked as it has been thus far.
However, since all this masking is essentially just an aesthetic matter,
I'm somewhat indifferent and open to removing the EXPERT dependency
as well; I'll let someone else make that call rather I.
