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.
pc98 case that I missed before. Attempt to get the irq for the PCIC
first from the loader env var and second from the config system. I've
been able to boot my laptop with a kernel that hardwired the irq to
10. This should allow boot -c to finally start working for pcic irq,
but I've not tested that. Add $FreeBSD$ to slot.h.
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.
will allow newbus based drivers to have pccard attachments. Also
start printing out probe messages for pccards stating the resources
used and regularize many of the pccard printfs.

o Add field to dev_desc for the size of the io port range. This isn't
used yet in the committed sources, but will make the transition easier
in the future.
If you build this into your kernel, you will need to rebuild pccardd.

This will trigger inserted()) to be called twice which confuses pccardd.
Add code to not process pcicitr())'s when in the middle of a resume

We do the same thing we do with all the other Vadem chips and print the
right identification for these chips. Tested with the 365, and inferred

This allows the cheapo PCMCIA card that I got from necx to print the right

(update_intr_masks might not need to be done in 3.X, but the new generic
interrupt code is incomplete w/regard to support for the PCCARD code, so
to avoid any potential problems use it. It can't hurt).
- Correctly register pcic_imask with the system interrupt code.
- Call update_intr_masks() so that pcic_imask modifications that occur
when card interrupts are registered get updated in the system
interrupt code.

2. pccard.c: PCIC_RESUME_RESET is now (also) a sysctl. (Never make it
a #ifdef if it can be made a sysctl!)
3. pcic.c: make getb() and putb() proper member functions of struct
pcic_slot. Add a couple of missing casts.
Use the name argument almost the same in all LKM types. Maintain
the current behavior for the external (e.g., modstat) name for DEV,
EXEC, and MISC types being #name ## "_mod" and SYCALL and VFS only
#name. This is a candidate for change and I vote just the name without
the "_mod".
Change the DISPATCH macro to MOD_DISPATCH for consistency with the
other macros.
Add an LKM_ANON #define to eliminate the magic -1 and associated
signed/unsigned warnings.
Add MOD_PRIVATE to support wcd.c's poking around in the lkm structure.
Change source in tree to use the new interface.
