As that is a while off, I'm providing this glue to * allow newbus drivers to have pccard attachments. * * We do *NOT* implement ISA ivars at all. We are not an isa bus, and drivers * that abuse isa_{set,get}_* must be fixed in order to work with pccard. * We use ivars for something else anyway, so it becomes fairly awkward * to do so. * * Here's a summary of the glue that we do to make things work. * * First, we have pccard node in the device and driver trees. The pccard * device lives in the instance tree attached to the nexus. The pccard * attachments will be attached to that node. This allows one to pass things * up the tree that terminates at the nexus, like other buses. The pccard * code will create a device instance for each of the drivers that are to * be attached. * * These compatibility nodes are called pccnbk.
