ba61c672f6 Shutdown a little better by commenting the shutdown code and acknowledging
any interrupts after we turn off the interrupt mask.

d9a423c36f Shut down the card bus bridge hardware on detach. Before we'd just
free the resoruces w/o actually turning off the interrupts.  This lead
to interrupt storms if you were to insert a card after kldunloading
the driver.

d9efa52e17 Make sure we set bst and bsh in the softc.
This gets us probing, but not attaching to, ISA cards.  More work
needed since the ISA attach routine is return ENXIO right now :-)

2ae7662803 Merge in WIP from p4 for supporting ISA pccard bridges conforming to
the ExCA spec, and close cousins:

o Write an activate routine that works.
o merge a couple of items from oldcard before they are lost
o write a deactivate routine

I suspect we're still a ways away from having this work, but maybe for
6.1/5.5?

f481fa4d29 MFP4: Changes to hopefully make the new power code work better
o Rather than just try to turn off EXCA_INTR_RESET, set the entire register
  to 0.  This is slightly faster, and a better hammer.
o Move attempted clearing of the output enable (EXCA_PWRCTL_OE) back to
  after we turn off the power.  Modify it to write 0 so that we don't get
  Bad Vcc messages on TI bridges (untested, but ru@ sent me a similar patch)
  while at the same time avoiding interrupt storms on Ricoh bridges (tested
  by me on my Sony).

# Many of my observations of 'breakage' for this patch are due to some bug
# in the load/unload of cbb.ko unlreated to this change.  I'll be investigating
# and fixing that bug in the fullness of time.

b32757b431 o The ricoh bridge needs us to turn off the function interrupts for
16-bit cards when we're powering them up.  Other bridges may have
  similar issues, so we do this for all of them by setting the
  interrupt in the PCIC register 3 to be 0 (done always anyway)
  and turning on the bit in the bridge control register to route these
  interrupts via the ISA bus (or via the interrupt configured in the
  PCIC register 3).  '0' means disable completely.  There's a small
  chance this may interfere with the o2micro power hacks, but I'll
  wait for reports to come in from o2micro users.
o Expand some of the comments about why we do certain things.

# this gets rid of the interrupt storm warnings on my 505TS.  I think
# that we may need to do something similar on suspend, but I'm unsure
# since I don't have a laptop that supports suspened/resume with a
# ricoh chipset in it.

85ef2343c4 The CD interrupt should only be enabled after we've initialized the
card.  Mask it while we're doing power things, as the PC Card standard
suggests.  Also, poll the POWER_CYCLE bit 10x a second as well as
providing a timeout for power cycle interrupt to happen.

The Ricoh '475 that I have doesn't seem to generate an interrupt for
power at the present time, so the polling is necessary for reasons as
yet unknown.  This results in an interrupt storm warning that I'm
still trying to quantify (the o2micro trick doesn't work to mitigate
this storm).  At the very least, this should help those users that
lost pccards on boot with the prior rev of this code.  My VAIO
PCG-505TS is now happier, but more investigation is necessary.

fd4e475233 Omnibus power and interrupt fixes:
o Don't busy wait on powerup.  Instead, use the power up interrupt to wait
  for the card to power up.  Don't wait when we're turning the card off,
  since no interrupt happens in that case.
o Convert many of the long DELAYs to tsleeps.  We do not run before
  the timer have stared, so DELAY isn't necessary.  More DELAYs can likely
  be eliminated in the future.
o When powering up the card, don't do anything if the card is already
  powered up (before we'd power cycle it).  This means that for most
  cards we power them up once and then never change the power.
o On card eject, mask (by clearing) the CD bit.  Before we set it, which
  was wrong.  We don't want to see any CD events past the first one since
  they need to be debounced.

With these changes, I can insert/eject 16bit cards without glitching xmms'
sound output.  Something very important to the development of better pccard
drivers :-)

3f7d3c1e3c Since cbb implements the pcib_ interface, it must also implement the
pcib_route_interrupt interface.  Since there's only one interrupt pin
in the CardBus form factor, everybody gets to share it.  Implement
cbb_route_interrupt to return the interrupt we have.

2a829b00f4 Now that we have the resource allocation code in current, the kludge
to try to allocate things on my parent can be taken out.  It duplicates code.

Also, add comment about why the power state stuff is here (type 2
devices don't participate in the power state save/restore due to
larger Bx issues).

6c92cac930 Start programming the bus numbers for the pci<->cardbus. When the
secondary bus is 0, we program the primary bus, the secondary bus and
the suborindate bus.  This isn't ideal, since we start at parent_bus +
1 and store this in a static.

Ideally, we'd walk the tree and assign bus numbers.  However, that's
harder to accomplish without some help from the bus layer which we're
not planning on doing that until 6.

This fixes my CardBus problems on my Sony PCG-Z1WA, and might fix the
Dells that have had problems.
