allows us to properly parse cards with attribute memory based CIS that
before wouldn't parse correctly, sometimes with a panic. This allows
me to get my 3C562 modem/ethernet card to fail to attach due to
problems in the ep and sio drivers rather than due to problems in the
CIS parsing code :-).
We weren't setting the address to jump to for the function entries.
This caused us to only work when the addional entries were after the
first ones. On the 3C562/3C563 card this was not the case.
We were also mapping Attribute memory when common memory was asked for
in the target of the LONGLINK_{A,C} or LONGLINK_MFC.
My IBM Home And Away Modem/LAN card still fails for reasons unknown.
o Call bus_generic_setup_intr and check its return value. Don't setup
func until we successfully get the interrupt from our parent.
o Add comments about some maybe questionable stuff so I can check later
to make sure that it really is that way.
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
This is the first part of a two-part update to NEWCARD. Changes in this
commit are non-functional, and includes the following:
* indentation and other changes to meet style(9).
* other minor style consistancy changes
* addition of comments
* renaming of device_t variables to be consistant across all of NEWCARD.
(note that not all style violations are fixed in this commit -- those that
aren't will be clobbered by the next commit.)
we need to delete the info from the list as well as zero out the res
pointer we saved in the code.
Also made a few style(9) changes while I was at it. Don't use if
(ptr) or if (!ptr), but compare against NULL. Compare against NULL
rather than 0. Don't have useless blocks.
There are likely other problems as well, but at least the wi based
wireless card with memory listed in its cis doesn't panic the system
when the card is inserted.
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.

The pccard_function_init() call creates a bunch of inactive resources
that are persistant and configured on demand. When the child driver
"allocates" a resource it is connected up to one of these. When the
child releases the resource, we should not delete our copy, just
deactivate it again. Otherwise there is nothing to recreate it again
after several probe functions have run and done an alloc/release cycle.
INVARIANTS shows 0xdeadc0de without this.
More work is needed to do a sweep though the pccard_function_disable()
call to actually delete the resources for real. Right now, we leak
memory on eject (at best), so Dont Do That(TM) yet. This affects
16 bit pccards on a cardbus bridge only. This will be fixed soon, but
for now it gets the cards working.

to conform to style(9), plus one other convention that I use:
o Declare variables at the start of the function, rather than in blocks
when it doesn't help understanding (mine).
o 80 column limit.
o BSD style statement continuation, rather than "gnu" style.
bus to use. We need to set it here.
This fixes the problem where a probe routine establishes and
disestablishes the interrupt and then we get a panic in the probe
routine.
However, we pass the pointer to the interrupt hanlder count to the
parent bus, which writes its own cookie there, so there may be some
problems with that which isn't apparent at the moment.
Commit made from: laptop running NEWCARD with sn driver (which works,
but gets the wrong ethernet address).
o Fix OLDCARD to use the new interface.
o Rename the offsetp argument to deltap to more closely reflect what it
is returning (it returns the delta from the requested value to the actual
value).
o Remove duplicate $FreeBSD$ in pccbb.c
o Allow deltap to be NULL.
o Convert new isa pcic driver and add XXX comments that this function isn't
actually implemented there (which means that NEWCARD pccard stuff won't
work there until it is).
o Revert attempts to make old inferface work in NEWCARD.

Adjust new code to cope with the older interface.
If the interface changes in the future, it ***MUST*** be cleared by me

- 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
o Change name of bus
o Change the panic on resource allocation failure to just a message. We'll
work out why this fails later in the pcic/pccbb code merge.
o Report function number and config index on probe line
o Activate the resources (I hope) when RF_ACTIVE is set on those resources
I'm allocating on behalf of my children.
o Always enable interrupts on multifunction cards in the multifunction
register.
o Remember the resources we allocate for the config entry.
o When we get the resource, do an resource_list_add and do a
resource_list_delete if we fail later in the resource list.
o In the pccard bus, we allocate the resources. When a child asks for
them, just return the resources that we allocated (thanks to Paul
Richards and Mike Smith for the idea).

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.
compat probe routines to work).
o Have a null driver_added routines. We need to be careful about probing
until after we know we have a card. For the moment, we do nothing
(which is safe). This fixes a panic when a driver is loaded w/o a
card in the slot.
XXX still need to fix the resource list code. It is totally busted and
XXX causes a panic in the child printing routine after the probe has

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.

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.

Add support for the SOHOware PCMCIA Ethernet card, model ND5100-E.
This seems to be a re-badged NDC (National Datacomms. Corp) card.
It needs a quirk entry due to lack of manufacturer tuple in the CIS.
For some reason, the 'Tx/Rx' LED on the connector module is inverted
such that it is off during network activity...
