3a6352bdee checkpoint latest pccard/pcic hacking:
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.

1b23908082 Fix pcic_detach_socket to get right pcic_handle.
Pass sc->dev rather than a bogusly cast pccard_softc *sc.

This allows us to insert and remove cards w/o panicing the kernel.
However, the cis isn't mapped in, so the pccard_scan_cis function
fails.

0d1337c6fa Be consistant about using the right child to get the ivars, which is
the pcic_handle structure for the socket.

82af5353b0 Add some comments about things that have become bad as I've been
working on this code, or things that I think are layering violations.
Plus a minor whitespace cleanup in one place while I'm at it.

deae2aaf91 Checkpoint of today's changes. We now get to the point where the pccard
layer is trying to access the now unexistant chip functions.
o Added DEVPRINTF which is like DPRINTF only calls device_printf.
o Made it possible to define PCICDEBUG
o Remove ph_parent and use the softc pointer sc instead in pcic_handle.
o Remove all references to dv_xname
o Add some debug messages.
o enable MI attach/detach calling for pccard.
o convert pcic_chip_socket_{en,dis}able to pcic_{dis,en}able_socket
  and connect them to the power_{enable,disbale}_socket.
o Remove pccard pointer from pcic_softc.
o GC some unused pccard functions.
o Convert pccard_chip_socket* to POWER_ENABLE_SOCKET
o kill pccard_attach_args.
o power_if.m updates.  More to come.

fe98624bbb Connect interrupts and start processing them. We panic on card removal
now, but we're getting interrupts!
o Add pcic_suspend/pcic_resume so we can detach our children on suspention
  and fix the state of the pcic on resume.
o Remove some unused parts of softc.
o Centralize resource activation/deactivation for pcic bridge chip in
  the stylistic pcic_activate/pcic_deactivate.
o Add bus_print_child method so we can see the pccard attachment.
o Add pcic_identify in an attempt to make it possible to automatically id
  the pcic devices.  This works great, but we cannot divine the irq to use
  from this method, nor the memory hole.  For the moment, KLUDGE irq to be
  10 and memory hold to be 0xd0000.
o Loose the pnp probe stuff.  This may be a big mistake, but it is easy
  enough to add back later.  I did this so the identify routines can do their
  thing unmolested by pnp information.  The whole identify thing may be a bad
  idea to be ripped out later.
o change return type of pcic_intr to void, make it static and ripple
  this through the code.
o Add explicit call to bus_generic_attach at the end of pcic_attach to
  get any children probed/attached.
o add some comments about future directions/questionable things being
  done at different layers, etc.

5882e70cb6 Delay creation of threads until after the idle thread is created, more
or less.  This is a kludge because there is no support for delayed
creation of threads early in the boot process.

NEWCARD new boots and the thread process starts and is visible from
ps.

Now, on to dev/pccard.

774af807e4 Make attach work, almost. Calling kthread_create from a
config_intrhook_establish doesn't work.  Children aren't yet attached
properly, but that's ok because pccard would likely panic in its
current shape.
o Save dev of pcic early in attach process
o save dev in pcic_handle for use in pcic_create_event_thread.
o Remove direct attachments of pccard children for now
o move establishment of pcic kthread to config_intrhook.

8aa39df106 o Hide pcic_chip functions inside file
o Attach children in a better way than before.
o Remove some dead code
o collapse the socket attach routines into pcic_attach

209cbfd3e6 o Separate out alloc/release from the activation
o minor formatting nits
o remove the bus_map/unmap calls.  FreeBSD doesn't need them.
o Fix most of the compiler warnings remaining (some still remain, but they
  are releated to calling functions that are going to change, so I did
  not bother).

e166a0bd06 Merge _isa and _isasubr since only one function remained in _isasubr
Saticize _isa.c
Kill compile warnings for _isa.c
Remove obsolete comment from i82365.c

ef8e4c1291 o Implement IRQ activation. We do this in bus_{setup,teardown}_intr,
per discussions on -arch.  This is different than -current's pccard
  code, but shouldn't have any real difference.
o More code cleanup.

Next step: convert bus_space_* mapping stuff to newbus.

810473943f Tonight's cleanups.
o Implement memory and I/O activation/deactivation.  irq not handled.
o switch pcic_chip functions around to use more convenient types.
o kill __P and most of the old K&R prototypes just to be mean.
o minor other nits

f27f6c0076 Add resource activation routines to pcic driver. Minor cleanup of
socket attach code.  We now have at least a chance for pccard devices
appearing in the future.

This is a snapshot of ongoing work.  Proceed at your own risk.

fac207b0b2 Make these compile. Next step is to connect newbus plumbing. 1999-10-27 05:24:09 +00:00

dc781fe4ff Very preliminary pcic device support. Will make depend, but won't
(yet) compile and link.  Renamed pcic back to pcic from pcicx, but
conditionalize its inclusion on pccard being included also.  card is
the old and pccard is the new, which is a handy way to have both in
the tree at the same time.
