Okay, I have two versions of the patch. One which follows the PC_FDC
patch and adds something like this to arch/<somearch>/Kconfig:

config ARCH_MAY_HAVE_PC_PARPORT
	def_bool y


The other version adds:

config ARCH_MAY_HAVE_PC_PARPORT
	bool

to arch/Kconfig (or maybe that should be in drivers/parport/Kconfig) so
that the various arches just need to select it.

Is there any preference for one over the other?
