pccard layer and rename them PCMCIA_CARD and PCMCIA_CARD2 respectively
(note, this is being done with an eye towards NetBSD integreation so
it is easier to keep lists of cards between us and them in sync).
Use this in the an and wi drivers.
Briefly, the significant changes include:
* Way better resource management in pccbb, pccard and cardbus.
* pccard hot-removal now appears to work.
* support pre-fetchable memory in cardbus.
* update cardbus to support new pci bus interface functions.
* Fix CIS reading to no longer use rman_get_virtual().
What's not there, but in the works:
* pccard needs to do interrupt properly and not read the ISR on single
function cards.
* real resource management for pccard
* a complete implementation of CIS parsing
* need to look into how to correctly use mutex in pccbb
pccard in the kernel for those drivers with pccard attachments. This
makes the compat layer a little larger by introducing some inlines,
but should almost make it possible to have independent attachments.
The pccard_match function are the only one left, which I will take
care of shortly.
- pccbb no longer needs to remember whether a card is inserted.
- pccbb reissues insertion on load of cardbus/pccard modules.
- got rid of unnecessary delays in power functions.
- Cardbus children are no longer deleted if probe/attach fails.
- non-attached child devices are reprobed at driver_added.
* CARD interface to read CIS
- added card_cis_read/card_cis_free interface to read arbitrary CIS
data. This currently is only implemented in cardbus.
* pccard begins to work
- pccard can now use higher memory space (and uses it by default).
- set_memory_offset interface changed.
- fixed ccr access, which was broken at multiple locations.
- implement an interrupt handler - pccard can now share interrupts.
- resource alloc/release/activate/deactivate functions gutted: some
resources are allocated by the bridge before the child device is
probed or attached. Thus the resource "belongs" to the bridge, and
the pccard_*_resource functions need to fudge the owner/rid.
- changed some error conditions to panics to speed debugging.
* Mutex fix - Giant is entered at the beginning of thread
before the attach. Things aren't completely working, but this is a good
checkpoint.
Also, initialize the dev member of the function as soon as we add it
to the parent.
o initialize ivars with bzero.
o remove interrupt function pointer. netbsd needs it, but we don't.
o add lots of comments about bogus things that I've been kludging to try
to make the simple cases work.
o add new ivar accessor for cis4 to match cis3. likely neither will be
needed, but it doesn't hurt to have it.

o Expand the pccard matching routines to include the ability to match
against the CIS strings since our current driver database is based on
that.
o Add lots more ivars to get the information necessary to snag these values.
possible to have different probe/attach semantics between the two
systems and yet still use the same driver for both.
Compatibility methods for OLDCARD drivers. We use these routines to make
it possible to call the OLDCARD driver's probe routine in the context that
it expects. For OLDCARD these are implemented as pass throughs to the
device_{probe,attach} routines. For NEWCARD they are implemented such
such that probe becomes strictly a matching routine and attach does both
the old probe and old attach.
compat devices should use the following:
/* Device interface */
DEVMETHOD(device_probe), pccard_compat_probe),
DEVMETHOD(device_attach), pccard_compat_attach),
/* Card interface */
DEVMETHOD(card_compat_match, foo_match), /* newly written */
DEVMETHOD(card_compat_probe, foo_probe), /* old probe */
DEVMETHOD(card_compat_attach, foo_attach), /* old attach */
This will allow a single driver binary image to be used for both
OLDCARD and NEWCARD.
Drivers wishing to not retain OLDCARD compatibility needn't do this.

sn driver updated more than minorly. Add module dependencies to allow

that it looks for an acceptible one. Once it finds it, it should set
the resources for the device. I say "should" because I've not written
that. Also set an ivar for the child of pccard. Minor fix to the
attach message printed, we lose the slot number, which I'll have to
restore later. Adjust the pccard ivar so that we can save the
function that corresponds to this driver so we can enable and disable
it more easily. Save a pointer to the function so we know what we're
dealing with.
There should be some way for the driver to specify which cfg it wants
to activate. For now the pccard_function_init function just picks
one, but we'll have to revisit this going forward. I'm not doing it
now because I'd need some way to activate the card many times and I'm
not sure that is desirable or even safe with some cards.
I've done this by having requests to allocate memory propigate up the
tree. We'll see how well this works and reevaluate if it isn't
working well. Also initialize ptr in the tuple. As well as minor
reorg of memory allocation. Likely need to do similar things for I/O
when the time comes.
I've move all defines from pccardchip.h into pccardvar.h and
eliminated pccardchip.h.
o Eliminate cross calls between the devices. Instead move to using the
newbus messaging system. Added three new card calls: attach_card,
detach_card, get_type.
o Eliminate interrupt routine in pccard we never use.
o Move from deactivate to detach for removing cards.
o Start mapping CIS memory, but it is broken and causes panics. At least
it is closer to working than before.
o Eliminate struct device everywhere. It was bogus.
o Initialize softc for pccard device so we have valid pointers to
ourselves.
o Implement routine to find the pcic ivar for a child device of the pccard so
we can use it to talk to the pcic hardware.
o Lots of minor tiding up.
This version now panics when we try to read the CIS. The next batch
of work to make this work is what was outlined in my posting to mobile
about resource allocation and such.

but I renamed it to pccard and made it compile on FreeBSD -current. I
converted SIMPLEQ to STAILQ as well as a few sc->dev.xname ->

I derived this work from the FreeBSD newconfig project
(http://www.jp.freebsd.org/newconfig). Any problems with it are
likely introduced by me.
