42e5f2f287 Merge from P4:
o Update copyright.
o Add a tunable to allow the ti12xx to initialize the pci clock.  Some rare
  cards need it.
o rename 67xx -> 6729 since there's really only one chip in this family.
o from pcic_pci_pd6729_init call the routing code
o Fix some comments out routing on the TI-1130 class (1030, 1130 and 1131)

MFC: After RE@ says it is ok.

9f977fb187 Add support for writing to mapping high memory for pccard memory
windows.  Right now we only support pci chips that are memory mapped.
These are the most common bridges in use today and will help a large
majority of the users.

I/O mapped PCI chips support this functionality in a different way, as
do some of the ISA bridges (but only when mounted on a motherboard).
These chips are not supported by this change.

80a97bd996 Some strange hacks for the clpd6729:
o It needs to have pcic_isa_intr intrrupt handler
o for pci interrupts, in the func interrupt handler it needs to check the isa
  registers rather than the pci ones for card present.
o better commentary for some of the strangeness of the 6729 on pci
o fix some crunchy comments to better reflect reality.

With this I almost have the WL200 working, but an interrupt storm
after attach is causing problems for reasons unknown.  This code
doesn't seem to break the normal clpd6729 case, and I'd like others
with 6729 cards to try to test it (there were some that were used for
external pccard slots in pci only systems).

d9619df632 o Remove workaround that I put in to mask the BadVcc problem.
o Add preliminary support for Cirrus Logic CL-PD6729 using PCI
  interrupts.  To use it you you need to set hw.pcic.pd6729_intr_path
  to 2.  This is allow us to still default to ISA intrrupt path for
  this part (which is found much more often in laptops using ISA IRQs).
  But some PCI cards have this part on them and this should allow them
  to be used.  It is untested on PCI, but it seems to not break the ISA
  case.
o Better sysctl descriptions (I hope).

d65d5bbff5 Lots of people have had to hack around the fixed address for cardbus
bridges in modern hardware (that hardware w/ lots of RAM).  Raise the
address from 0x44000000 to 0x88000000 to match what we do with
NEWCARD.  However, this really should be done in the pci layer.

1d88dfe265 What:
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.

Extra Special Thanks To: Scott Lamber for his kind and generous loan
of a Toshiba laptop with a ToPIC 100 in it for my use.

93da209126 o Try to do 3.3V support better for the 6722 and 6729/30.
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]).

# fix them.

Tested on the 6722, but not the 6729.

d1cf40403a Restore the main BAR for the bridge on resume. Some machines don't save
this accross suspend/resume events and this was causing the dreaded false
positive hit on my "static bug" test.

Note: the PCI bus code should do this for us.
Note2: We don't do the same for I/O based pci devices since it is
more code and doesn't appear to be necessary.

7cf44afd1a <jkh> "Hey Rocky, watch me eject this pccard outta my laptop!" "What,
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).

98435cf714 Patric Gualat tells me that I can't do basic bit math. He's right.
When either bit 3 or 4 is set, we need to *SET* bit 5, not clear it in
the card control register.  This makes TI PCI-1030, 1130 and 1131 not
work anymore without this fix.

592823383b Move to using a chip function + function pointers to deal with the
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
Shibata-san's power handing patches posted to bsd-nomads:15866.

MFC: Soon, if possible.

afd9750bfd A number of fixes for the TI-1130 and ISA interrupt routing cases:
o For TI PCI-1130, you need to set bit 5 of register 91 if you want
  ANY pci interrupts.  Then set bits 3 and/or 4 as appropriate.  This
  will fix those people with 1030, 1130 and 1131 in their machines
  trying to do PCI interrupts.
o Fix case where we were trying to automatically fail back to ISA
  interrupt routing.  We were dereferencing a NULL pointer.  This
  was true of ANY chipset.
o The bus_setup_intr method needs to be pcic_setup_intr so that "FAST"
  interrupts fail on PCI case (modems act flakey if we don't force
  them to fall back to normal interrupts).  Also needed so that the
  proper ISA IRQ can be set in the ExCA register.  This fixes the
  people whose ISA routing was failing[*].
o When we find a generic yenta/pccard bridge, go ahead and print its
  vendor ID in boot verbose.

Machine with theses symptoms and a serial console by: jedgar

[*] Looks like my pc98 machine has some interrupt source on IRQ 15
that gave about 30 interrupts per second, which masked this problem on
my PC-9821Nr15.

0b370908b2 First cut at getting the ISA routing working. If we can't route a PCI
interrupt for the CSC interrupt, then we revert to ISA.  If we didn't
have an interrupt set up with hw.pcic.irq, then do polling.

Also, don't complain about ignoring function 1 for any devices except
pcic devices.  This would normally only show up if someone set
hw.pcic.ignore_function_1=1.

d625c99d74 Explain what we're doing in pcic_pci_shutdown a little better. Try to
explain the subtle side effects that are going to happen and why we go
ahead and ack the interrupt source.  This stuff is tricky to get
right.

Also, emperical tests have shown that doing a shutdown in attach to be
ineffectual, so remove it from there.  Analysis of the code paths
shows that nearly identical writes to these registers happen in later
parts of the code.  The hanging problem on thinkpads when we change
the interrupt routing type is something else.
