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.
