03599baeb2 Make pccardc beep actually work. The kernel was doing the wrong thing
with the beep information it had (like ignoring it).

Submitted by: sanpei@sanpei.org (MIHIRA-san Yoshiro)

Add $FreeBSD$ to pccard_beep.c while I'm here.

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.

b5137699ae Reorganize the attachement point for pcic (it was unattached and
floating before).  Attach pccard devices to pcic, one per slot
(although this may change to one per pcic).  pcic is now attached to
isa (to act as a bridge) and pccard is attached to pcic, cbb and
pc98ic (the last two are card bus bridge and the pc98ic version of
pcic, neither of which are in the tree yet).  Move pccard compat code
into pccard/pccard_compat.c.

THIS REQUIRES A CONFIG FILE CHANGE.  You must change your pcic/card
entries to be:
# PCCARD (PCMCIA) support
controller	pcic0	at isa?
controller	pcic1	at isa?
controller	card0

The old system was upside down and this corrects that problem.  It
will make it easier to add support for YENTA pccard/card bus bridges.

Much more cleanup needs to happen before newbus devices can have
pccard attachments.  My previous commit's comments were premature.

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).

075a76a29e - Instead of relying on a functional call to register PCARD-capable drivers,
use a Linker Set.  Note, if a driver is loaded as an LKM  if will have
  to use the function call, but since none of the existing drivers
  are loadable, this made things cleaner and boot messages nicer.

c669d2df7e - 'Beep' support now happens in it's own separate file, so you can mess
around with different noises for the different events and not have it
  affect other files.

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.
