o ToPIC is happy with two cards now, even when the two cards are
modems.
o Fix (all?) hangs on boot when power is applied to the card. I
suspect that this will make the Ricoh bridges happier and also
make a lot of VAIO owners happy (confirm to me in private email
please :-).
o All Cardbus bridges should now support 3.3V, X.XV and Y.YV cards,
to the extent that the underlying hardware supports such cards.
(X.X and Y.Y haven't been assigned values yet :-).
o Better 3.3V support for Ricoh ISA bridges.
How:
o Don't mess with the power register when scanning the cards. It
is unnecessary and causes BADVcc conditions on many chipsets. These
in turn can cause an interrupt storm.
o Make pcic_disable reset the slot's voltage.
o Move initializing voltage for the slot until after it has been
disabled.
o Fix a lot of issues with the pcic_cardbus_power routine. We
now properly enable the card and take it out of reset after
a power change.
o When detecting the card's voltage, if we're in a BadVcc state,
direct the bridge to rescan the card for what it supports.
(we might need to in the future set the power register to 0
before doing this).
o Don't preserve CLKSTOP. need to revisit this.
o Better support for Ricoh ISA bridges for 3.3V cards.
o Don't write to PCIC_POWER directly as offten, but instead go
through the pcic_power interface.
o All cardbus bridges now default to use cardbus power control.
o Add misc register definitions.
o remove some (now) bogus comments.

general cleanup of the API. The entire API now consists of two functions
similar to the pre-KSE API. The suser() function takes a thread pointer
as its only argument. The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0. The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

detect 3.3V cards for the 6710 and another method for the 6722. This
latter method is also how the 6729/6730 is supposed to detect 3.3V
cards. This method works great on my Fujitsu Stylistic 500. Sadly,
it appears that not all laptop makers are as detail oriented as the
folks that made the Stylistic. IBM Thinkpad 701C and AST Asentia 810N
both hang hard when the 6729 method is used, but at least the thinkpad
works when the 6710 method is used. The failure mode appears to be any
access to the memory that we've mapped the CIS in causes the machine to
hang until you eject the card. The Thinkpad, at least, works with this
change, and it doesn't break my Stylistic.

value (-1) in lue of 50 (which assumes a 5.0V card). The rest of the
pccard system doesn't detect the proper voltage for the card, so we have
to do it on powerup. Many (all?) 3.3V cards can tolerate 5.0V for reading
the CIS, but may fail to operate properly when so powered.

o Bite the bullet and create controller types for the 6729 and also for
the 673x. Rename the 672x to 6722.
o Define minimal extended register info (just register 0xa for reading VS[12]).
# I think the last version may have broken 673x controllers, but this should
# fix them.

on my CL-PD6722, but won't work on the CL-PD6729. The latter two need
more sophisticated detection of 3.3V cards than I'm up to at the
moment. Also, only a few of the ISA chipsets that support 3.3V will
likely work at the moment.
It appears that for 3.3V cards we must detect them and adjust the
pwr.vcc value from 50 to 33. Give a strong hint to automatically
power up the card for PD_POWER cards.
This makes my SMC 2602W (the 3.3V version of the 2632W) work on my
Fujitsu Stylistic 500.

Note: the PCI bus code should do this for us.

more code and doesn't appear to be necessary.

o Move initialization of the slot bst and bsh to inside the for loop.
o move sc there as well.
o Remove debug printf that prints the ID of the first slot twice.
o Use the sp for the relevant slot in getb, rather than for the 0th slot.
again? That NEVER works!" "This time for sure!"
Minor overhaul of how we do interrupts for the pci interrupt routing
case to cope with card ejection better (read: make it not hand on so
many cards):
o Reintroduce func_intr and func_arg and use the to store the
interrupt handler to call.
o Create a pcic_pci_func_intr to call the real interrupt handler
iff the card hasn't been ejected.
o Remove some checks in pcic_setup_intr now that it is used
exclusively for isa routed interrupts.
o Defer the eject event until later too, but make sure we can't
do any client driver ISR calling in the interrum.
o Add some simple code to make sure that we don't attach more
than one child. This should fix pccardd starting twice
problem (ala single user -> multi-user when you started pccardd
by hand in SU).

When either bit 3 or 4 is set, we need to *SET* bit 5, not clear it in

help with the hanging problem on reboot. Note: we need to do the
other things as well. Also, turn off the bits in the stat change
interrupt mask and the cardbus interrupt mask as well in an attempt to
shut off all interrupt sources.

function and csc interrupt routing path (eg, ISA or PCI) so that we
can more easily switch between the two.
When we don't have a card ISR, put the function interrupt into ISA
mode. This effectively masks the interrupt since it happens once, and
not again until we have an ISR. This should help hangs, and might
help people that unwisely update the kernel w/o updating pccardd.
This is done at mapirq time.
Force CL-PD6729/30 to use ISA interrupt routing and maybe even detect
the number of pccard slots properly (this is still WIP). We aren't
going to support PCI interrupts for this release. A future release
should support them, however. Shibata-san's 3.3V fixes are not
included.
Add a hack which should, in i386, rewrite IRQ 0 cardbus bridges to be
IRQ 255, which should cause interrupts to be routed. This is mostly
untested since my one tester disappeared after reporting nothing
changed.
Implement, but do not use, a power method called cardbus. It looked
like a great way to get around the 3.3V problem, but it seems that you
can only use it to power cardbus cards (I get no CIS when I enable it,
so maybe we're programming things bogusly).
GC the intr and argp stuff from the slot database.
Improve the ToPIC support with the power hacks that Nakagawa-san
published in FreeBSD Press and that Hiroyuki Aizu-san ported to
-stable. The ToPIC hacks were for 3.3V support in ToPIC 100, but it
looks like the '97 also has identical registers, so use them too.
Add some #defines for the cardbus power stuff.
Finally implement making CSC on the Ricoh chips ISA or PCI. This will
allow polling mode to work on vaios, I think.
Add some minor debugging. This should likely be cleaned up or put
behing a bootverbose.
Some of this work, and earlier work, was influanced by Chiharu
