o Add Vpp power at 5.0V rather than 0. Setting it to zero violates the pccard spec. Most pcic devices in use today don't let us violate the spec, but some older ones do. Bill Paul sent this to me a long time ago and I thought I'd commit it before now. o Add some debug stuff hidden behind bootverbose.

|
* 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.
