will allow newbus based drivers to have pccard attachments. Also start printing out probe messages for pccards stating the resources used and regularize many of the pccard printfs. Reviewed by: Peter Wemm.

|
* 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.
