On arm that should only be set on a couple of subarchitectures, but
we can fan that out after your patch goes in, just like you do for Mips

Similar to ARM and Mips.

Highly unlikely, except through PCI.

Certainly not, no PIO support

Only through PCI

Probably not.
I think you can leave these four out right away, provided you add
the section below:

As you write, anything that has PCI can theoretically take parallel ports,
so I would always list PCI here as a way to get it anyway. Probably also
ISA and PCMCIA. How about adding this?
config HAVE_PC_PARPORT
bool
default (PCI || ISA || PCMCIA)
