34# Companion interface for pccard.  We need to set attributes for memory
35# and i/o port mappings (as well as other types of attributes) that have
36# a well defined meaning inside the pccard/cardbus system.  The bus
37# methods are inadequate for this because this must be done at the time the
38# resources are set for the device, which predates their activation.  Also,
39# the driver activating the resources doesn't necessarily know or need to know
40# these attributes.
