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.
Subitted by: peter (Parts of the new version code)
by even a compile of the OLDCARD code, was unapproved by me the keeper
of OLDCARD and broke OLDCARD and the ray driver.
Adjust new code to cope with the older interface.
If the interface changes in the future, it ***MUST*** be cleared by me
so that the OLDCARD impacts taken into account. It code in card_if.m
is used jointly by both OLDCARD and NEWCARD.
- 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
- Remove redundant header-type-specific support in the cardbus pcibus
clone. The bridges don't need this anymore.
- Use pcib_get_bus instead of the deprecated pci_get_secondarybus.
- Implement read/write ivar support for the pccbb, and teach it how
to report its secondary bus number. Save the subsidiary bus number
as well, although we don't use it yet.
- Make pccbb/cardbus kld loadable and unloadable.
- Make pccbb/cardbus use the power interface from pccard instead of inventing its own.
- some other minor fixes

This doesn't work with 16bit pccards under NEWCARD.
Enable in your config by having "device pccbb" and "device cardbus".
(A "device pccard" will attach a pccard bus, but it means you system have
a high chance of panicing when a 16bit card is inserted)
It should be fairly simple to make a driver attach to cardbus under
NEWCARD -- simply add an entry for attaching to cardbus on a new
DRIVER_MODULE and add new device IDs as necessary. You should also make
sure the card can be detached nicely without the interrupt routine doing
something weird, like going into an infinite loop. Usually that should
entail adding an additional check when a pci register or the bus space is
read to check if it equals 0xffffffff.
Any problems, please let me know.
