INTERFACE card;

#
# Companion interface for pccard.  We need to set attributes for memory
# and i/o port mappings (as well as other types of attributes) that have
# a well defined meaning inside the pccard/cardbus system.  The bus
# methods are inadequate for this because this must be done at the time the
# resources are set for the device, which predates their activation.  Also,
# the driver activating the resources doesn't necessarily know or need to know
# these attributes.
#
# XXX A nagging doubt in the back of my mind suggests that these sorts of
# XXX things might be able to be done with ivars.  This nagging doubt doesn't
# XXX offer a good way to actually do this, but remains nonetheless.
