e6e2fdce18 Copy manufacturer and version string into the kernel, and copy it to
the slot info.  This brings OLDCARD's API much closer to NEWCARD and
will allow moving more information into the kernel from pccard.conf
for common drivers (ed).

8fe085c7ec Rearrange previous commit that passed the vendor id to the kernel in a way
that's binary compatible for -stable.  While binary compatibility doesn't
matter much in -current, it is critical for -stable.  This change requires
pccardd/pccardc to be recompiled.

c1c1a23f53 Attempt to fix and document interactions between suspend/resume and pccardc
power x 0.

pccardc power x 0 used to disable the slot.  But a suspend/resume
would reactivate the pccard.  It no longer does that.  Now the
disabling of the slot is sticy until it is reset with power x 1 or the
card is ejected.  This seems closer to correct behavior to me.

o Process all card state changes the same using pccard_do_stat_change().
o Cleanup disabling the card so that we can preserve the state after
  the change.  Basically, don't set it to empty as often as we do.
o On suspend, the new state is "empty" and the laststate is "suspend"
o Document state machine with a diagram of states and edges.  The
  edges are labeld to tell the reader what event causes the external
  state changes.
o "machdep.pccard.pcic_resume_reset" may be obsolete now.  We always
  call the bridge driver's resume method on resume now.  Otherwise cards
  won't automatically show up.  If it needs to stay, I'll add it back.

7402675de4 First cut at bringing NEC PC98 original pccard bridge code back into
FreeBSD.  This code doesn't work just yet, but does compile.  We need
to start indirecting via the cinfo pointers, rather than directly
calling pcic_*.  There may be other issues as well, but you gotta
start somewhere.

36260de0cf Lots of minor cleanup, plus a couple of interesting things.
o Attempt to disable the slot when we detect that there are problems with
  it in our ISR.  This should make polling mode work better for more cards,
  but more work may be needed.  This "disabling" sets the card interrupt
  register to 0.  This worked for me for lots of tests in polling mode.
o Now that I've found datasheets, fix a boatload of magic numbers in the
  source to make it easier to understand.
o Use a table of names rather than a big case statement.
o Cull a few of the "unused" controller types that we map to other times
  that were a vestiage of PAO code that we never merged in the same way.
o Enforce legal IRQs.  You are no longer allowed to try to use IRQs that
  will fail on all known ISA/PCI <-> PCMCIA bridges.  The bridges do not
  have pins for these illegal interrupts, and all of them are listed as
  reserved and/or illegeal in the datasheets depending on which one you
  look at.
o Add comments about how IBM-AT based computers and NEC PC-98 based computers
  map these interrupts and which ones are valid.
o Always clear the bit that steers the management interrupt either to the
  value listed in the PCIC_STAT_INT register.  I've seen this bit get set
  on suspend/resume and after windows boot, and it does't hurt to clear it.
  NOTE: this might mean we can share this interrupt in the future.

595166f0f7 Add support for PnP ISA cards, and some laptop PnP support:
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.

Tested on: My VAIO and with the Linksys pccard reader.

d95b5da991 Switch to using suspend/resume methods rather than the APM hooks.
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)

4f76d87b21 Massive rewrite of pccard to convert it to newbus.
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.

Many thanks to Peter Wemm and Doug Rabson for helping me to fill in
the missing bits of New Bus understanding at FreeBSD Con '99.

35c0baa6b7 Remove name field from controller information. Fix name setting in
pc98 case that I missed before.  Attempt to get the irq for the PCIC
first from the loader env var and second from the config system.  I've
been able to boot my laptop with a kernel that hardwired the irq to
10.  This should allow boot -c to finally start working for pcic irq,
but I've not tested that.  Add $FreeBSD$ to slot.h.

b99d6b5edc Kludge together support for the old pccard system with newbus. This
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.

9dcbe2404a Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.

Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)

Add the correct hook for devfs to kern_conf.c

The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.

A few drivers had minor additional cleanups performed relating to cdevsw
registration.

A few drivers don't register a cdevsw{} anymore, but only use make_dev().

9b3df7693a Initial update pccard code for KLD module support. Module support
however is only marginally useful until the new-style bus (pci and isa)
stuff comes onboard to give us a better shot at actually pci and isa
drivers loadable (or preloadable anyway).

8bb7a8fc95 - Functional changes to PCCARD support.
* Kill individual drivers 'suspend' routines, since there's no simple/safe
   way to suspend/resume a card w/out going through the complete probe
   at initialization time.
 * Default to using the apm_pccard_resume sysctl code, which basically
   pretends the card was removed, and then re-inserted.  Suspend/resume
   is now 'emulated' with a fake insert/removal.  (Hence we no longer
   need the driver-specific suspend routines.)

e7e437dbfa - Do a bunch of gratuitous changes intended to make the code easier to
follow.
 * Rename/reorder all of the pccard structures, change many of the member
   names to be descriptive, and follow more closely other 'bus' drivers
   naming schemes.
 * Rename a bunch of parameter and local variable names to be more
   consistant in the code.
 * Renamed the PCCARD 'crd' device to be the 'card' device
 * KNF and make the code consistant where it was obvious.
 * ifdef'd out some unused code

cc6da87199 Update the PCIC controller's imask with individual slot IRQ's.
Assuming that the intr_mask[] was updated by changing the maskptrs (the
existing update_intr_masks() function will not work) this code was
written so the PCIC controller insertion/removal events will not
interrupt the card IRQ handler events.

Some possible scenarios:
+ Card is removed during IRQ handler:

  - PCIC card handler is allowed to interrupt
  - card removal event is called, removing the driver and data structures
  * card interrupt handler continues w/out driver, data structures, and hardware

OR (the code just committed)

  * card IRQ handler has no hardware to read/write to, but has code and
    data to run on (XXX- Assume it completes and doesn't spin forever)
  - PCIC card handler unloads the card driver

The current situation at least leaves the card interrupt handlers the
drivers and data structures to work with although the hardware can't be
guaranteed.

ceff12b4c4 Adds the APM hooks into the generic pccard kernel files. With this code
in place device drivers can now register power-down/power-up routines so
that we can use common routines to power-up/power-down cards for
