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.

pcic_attach() got a wrong pointer to pcic_slots since device haven't

Now we set unit number to pcic device first, then access to pcic_slots

o Remove include of opt_bus.h. It isn't needed and gets in the way of

- Fixed bogus CIS tuple dumping (Network node ID, IRQ modes and etc.)
- Include telling drivers ethernet address if Network node ID
tuple is available. This is usefull for some bogus ehter cards which
can't get correct ethernet address from CIS tupple.

There's still some issues with this code, so xe can't map the cis just

PCI/CardBus Bridge -> PCI-CardBus Bridge

cardbus bridge init routine for all cardbuses. This routine attempts
to compensate for BIOSes that do not setup the cardbus bridge into
legacy mode. Since this is becoming more common, and cardbus pci
cards have appeared on the market, this makes sense.
Do some TI113x specific initialization. This came in as part of the
patch. Report TI1[1234]XX specific config registers protected by
bootverbose.
Minor code cleanup while I'm here. I've also removed the unused code
present in the original patches, and cleaned it up slightly in places
as well.
The original patches supported more than one card, but these patches
support just one. We should likely revisit this in the future.
This makes the Compaq card that Walnut Creek CD purchased for me work
in my bouncer box.
This is a MFC candidate. However, I'd like to get some airtime on
these patches on as many laptops as possible before doing the MFC. It
does change things somewhat. In theory, apart from the minor TI
tweaks, this shouldn't change anything if the bridge is in legacy mode
already.

o break out some of the probe routine the allocation of resources
into an attach routine
o Recognize PnP ids
o Allocate IRQ per card rather than per system
o Better polling reporting
o Remove unneeded include files in slot.h
o store a pseudo unit number on each device we find.
o Pass a unit number to interrupt/timeout routine and use it for polling
the hardware.

For example, when /etc/pccard.conf had ed0 in config line, but kernel
refused this name and said
devclass_alloc_unit: ed0 already exists, using next availale unit
number
Kernel used ed1 as device name and it did not match with config and
insert/remove lines. Fortunately, dhclient was called without args,
and it works, but if we wanted to use static IP address for PC-card,
it did not work.
This modification makes pccardd to execute insert/remove lines with
the true device name that returns from kernel. (Last change to
etc/pccard.conf.sample eliminated all hardwired device name from
insert/remove lines in /etc/pccard.conf)

This makes the ed driver not enter its interrupt routine during the
probe. Apparently, an interrupt happens when you disable the
interrupts. There are other problems with ed still.
Should have no effect, but does make things a little cleaner. I
thought this was the race that was causing problems, but it turned out
to be in pccardd waking up after the empty/insert events had happened
and being confused.
Minor cleanup:
o Remove isahd from pccard_devinfo
o remove extra from controller
o formatting nits
o use PCCARD_DEVINFO(d) rather than a bare device_get_ivars(d)
as the unit argument instead of 0. disable_slot() calls
devclass_get_device() correctly, however because alloc_driver() does
it wrong, disable_slot() is unable to locate the child devices
attached to the pccard bus and thus fails to call device_delete_child()
on them. The end result is that when a card is removed, its detach
routine is never called, and re-insertion always fails.
With this fix (and the previous one to if_wi.c), I can now insert,
remove and re-insert my WaveLAN/IEEE card and things behave correctly.
kldunloading the if_wi.ko module also seems to work properly now.

device_add_child_ordered(). 'ivars' may now be set using the
device_set_ivars() function.
This makes it easier for us to change how arbitrary data structures are
associated with a device_t. Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.
Despite my best efforts I've probably forgotten something so let me know
if this breaks anything. I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

problem.
o Create new timeout routine so we don't detach the card inside a ISR
but instead drop back to spl0 via a timeout of 0.
o Actually delete the child of the pccard device rather than just faking
it badly.
o Fix sio, ed and ep to have pccard detach routines that are int rather
than void.
o Fix ep and ed pccard detach routines to use if_detach rather than just
if_down. if_detach destroys the device, while if_down just marks it
down. In this incarnation of the pccard things, we map the disable
the slot action to detach the driver, which removes the driver from the
device tree. When that is done, a panic would soon follow as the
ifconfig tried to down the device.
Didn't fix:
o Should cache the pccard dev child's pointer in struct slot
o remove now unused parts of struct slot
o Any driver using softc after detach has been called. sio's softc used
to be statically allocated, so you could check sc->gone, but that is
now gone.
o Didn't remove gone from softc of drivers that use the old pccard method.
Didn't test:
o ed driver changes
o sio driver changes on pccards
o suspend (no laptop or apm support on my desktop)
o Gut the compatibility interface, you now must attach with newbus.
o Unit numbers from pccardd are now ignored. This may change the units
assigned to a card. It now uses the first available unit.
o kill old skeleton code that is now obsolete.
o Use newbus attachment code.
o cleanup interfile dependencies some.
o kill list of devices per slot. we use the device tree for what we need.
o Remove now obsolete code.
o The ep driver (and maybe ed) may need some config file tweaks to
allow it to attach. See config files that were committed for examples
on how to do this.
Drivers to be commited shortly.
This is an interrum fix until the new pccard. ed, ep and sio will be
supported by me with this release, although others are welcome to try
to support other devices before new pccard is working.
I plan on doing minimal further work on this code base. Be careful
when upgrading, since this code is known to work on my laptop and
those of a couple others as well, but your milage may vary.
BUGS TO BE FIXED:
o system memory isn't allocated yet, it will be soon.
o No devices actually have a pccard newbus attach in the tree.
BUGS THAT MIGHT BE FIXED:
o card removal, including suspend, usually hangs the system.
