it would work), or a specialized one. Most of these have been creatively stolen from pccard_nkb, which in turn stole from isa showing that generic bus_ versions of bus_{set,get,delete}_resource might be profitable. Fix a couple of minor bugs introduced in the last round of updates from NetBSD. Start on the pccard_ivar structure which will hold the resources and slot number. Add tcic as a possible attachment for pccard and rename the attachment for pcicx to pcic since the name has changed since I originally wrote this stuff. Next up: stringing together the various memory and I/O allocation/mapping primitives in i82365.c, final touches on the isa attach routine and other fun stuff in that line of attach.
