1ead03c2ba Add support for changing the way that ToPIC csc interrupts are routed.
# Note: The ToPIC 100 and the ToPIC 97 datasheets are in disagreement
# as to if this bit is supposed to be set or cleared to enable INTA routing
# so I made my best guess.

Also, comments about the various chipsets, including some grumpy ones
about how vague the O2micro datasheets are.

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.

6ac061b532 Improve interlocking for card removal. We now can remove the card in
the ISR.  We keep track of the card state and don't call the IRS when
the card isn't inserted.  This helps quite a bit with card ejection
problems that Ian was seeing.

e423aa38ba For TI12xx and newer, clear register 0x84. This is the "Multimedia"
register.  It enables Zoom Video.  It appears that on at least one
card that Monzoon is using sets these bits by default.  Nothing works
when these bits are set, everything works when they are clear.

Add commentary on some of the ti bits.  Make code a little clearer.
Also remove a call to pcic_pci_pd6729 which was prematurely added in
the last commit.

82c38f3a43 Try to support the Cirrus Logic PD6833 better in pci mode. This is
done from the datasheets since I'm ahving problems with my laptop that
has the 6833 in it...

Minor rework of TI code.  Should be the same as before.

53af1c8a3d TI cardbus bridges, 12xx and newer, have an interesting register. It
is the diagnostics register at offset 0x93.  When bit 5 is set in this
register, bits 4-7 in ExCA register 0x5 being 0000 are required for
pci interrupt routing.  When it is clear, then bit 4 of ExCA register
0x3 is used to enable it.

The only other issue is that when you route interrupts this way, you
must read ExCA register 0x4 in order to clear the interrupt, else you
get an interrupt storm.

Deal with this requirement by setting things up.  It is believed that
this won't hurt other chipsets, but other chipsets may require their
own work arounds.

58c13f9b7a Add new pci attachment for pcic. This supports pci cards as well as
card bus bridges.

We now always use pci interrupts for pci cards.  This will allow us to
more easily configure things.  You must change your IRQ lines in
/etc/pccard.conf to match what we've probed.  I'm not sure the right
way to deal with this right now.

Development of pci pcmcia has been funded by Monzoon Networks AG.  I
am grateful for their generosity.

82d3fe450d When booting, turn on the 3E0 compatibility address for ricoh cardbus
parts.  This is based on the newcard code that turns it off :-).  We
can now reboot after NEWCARD or Windows and have OLDCARD work.  Add
support for the RL5C466 while I'm at it.

Treat TI1031 the same as the CLPD6832.  It doesn't work yet, but sucks
less than it did before.

Also add a few #defines for other changes in the pipe.

These were on cards that were pci pccard (not cardbus) bridges that
lived in SparcUltras that picked up on ebay.

6ea2fbe9be More fully initialize cardbus bridges. We now call the new generic
cardbus bridge init routine for all cardbuses.  This routine attempts
to compensate for BIOSes that do not setup the cardbus bridge into
legacy mode.  Since this is becoming more common, and cardbus pci
cards have appeared on the market, this makes sense.

Do some TI113x specific initialization.  This came in as part of the
patch.  Report TI1[1234]XX specific config registers protected by
bootverbose.

Minor code cleanup while I'm here.  I've also removed the unused code
present in the original patches, and cleaned it up slightly in places
as well.

The original patches supported more than one card, but these patches
support just one.  We should likely revisit this in the future.

This makes the Compaq card that Walnut Creek CD purchased for me work
in my bouncer box.

This is a MFC candidate.  However, I'd like to get some airtime on
these patches on as many laptops as possible before doing the MFC.  It
does change things somewhat.  In theory, apart from the minor TI
tweaks, this shouldn't change anything if the bridge is in legacy mode
already.

f88e599fcb Copy Texas Instruments cardbus controllers from pcisupport.c, the pcisupport.c
probes are at the 'chip' level and will get overridden by pcic_p if it is
compiled in. It's still nice to get the better probe message if it's not...
