/*
* This file contains various kludges to allow the legacy pccard system to
* work in the newbus system until the pccard system can be converted
* wholesale to newbus. 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. PCCard New Bus Kludge.
