built in, or as an addon card (My Japanese isn't quite good enough to
know which). [FreeBSD98-testers 5098] contains all the details.

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.

gets the cardbus code to compile, and I was successfully able to map
the CIS into high memory and probe/attach a 16 bit pccard.
Jonathan: feel free to replace this with your version if you want -
this is an expedient hack to get things to build and appear to work.
in the future:
o Remove pcic_softc from pcic_handle and replace it with a void *
o Reduce dependence on accessing softc via a pcic_handle
Minor cleanups:
o Define a macro to count the size of an array and use it.
o Minor whitespace alignment
o make no slots found a printf not a panic.
has the side effect of detaching the children before I delete them.
When I put the last commits in a loop for loop it died after 5 or so
iterations. After this change, I lasted 50 before I stopped the test.
Add pcic_detach which removes all of the pcic's children.
This lets me load/unload pcic multiple times w/o having multiple
instances of each slot attached to pcic.
problems). Also pick an irq if one isn't specified. Ditto for
memory.
Add additional printfs in the error paths. These will disappear in time.
There are still some panics, but this is a good checkpoint.
I've done this by having requests to allocate memory propigate up the
tree. We'll see how well this works and reevaluate if it isn't
working well. Also initialize ptr in the tuple. As well as minor
reorg of memory allocation. Likely need to do similar things for I/O
when the time comes.
I've move all defines from pccardchip.h into pccardvar.h and
eliminated pccardchip.h.
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.
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.
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.
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.
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.
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.
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).
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.
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
pcic_attach_sockets. Rework bus width probe mapping and unmapping to
use the newbus bus_{allocate,release}_resource with a rid of 1 to work
on FreeBSD. Remove a few now unneeded #includes.
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.
o Delete pcic1 from NEWCARD
o Add explicit resource hints to pcic0
o Get attach working with newbus, kinda (it does all the newbus stuff,
but doesn't try to attach the pccard yet, too many panics).
o Disable ie0 and le0 in NEWCARD config. There appears to be a bug in
the isa_compat code wrt memory conflicts with newbus drivers for
reasons unknown.
o Minor cleanups.
o Rewrite probe code to work in the newbus world.
o Add preliminary pnp support. I have no clue what the pnp ids for
the older ISA machines/cards. I don't have any of these cards/machines
so I'll have to rely on the user community to give me help.
o Minor code reformatting.
Attach hasn't been touched, and there may be some config issues that
we need to deal with as well. These will follow in time.
(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.
