94b197e96d Move the pcic interrupt from pcic.c to pcic_isa.c. The ISA handling
for card change interrupts is different than the pci stuff that's
coming soon.  Set the management irq in different ways.  If
pci_parallel interrutp routing, then use the PCI way of getting
interrupts.  Move polling mode into pcic_isa since when we're routing
via pci polling doesn't work because many bridges (systems hang solid).

If we're routing interrupts via pci, they can be shared, so flag them
as such.

Note, this doesn't actually change anything since the pci attachment
isn't quite ready to be committed.

f83a4e8171 Turns out that one bit isn't enough. Introduce two new fields
csc_route and func_route to hold the way that each interrupt is
routed.  csc is Card Status Change in the datasheets and standard, but
is called "Management Interrupt" in FreeBSDese.  There are three types
of interrupt routing:  ISA parallel, PCI parallel and ISA serial (some
chipsets support other types as well, but I don't plan on supporting
them).

When we try to allocate an interrupt, and the type for that interrupt
is pci_parallel, allow it to be shared by oring in RF_SHAREABLE to the
flags argument.  Introduce pcic_alloc_resource to allow this to
happen.

92d08a4dcf Allow a shareable interrupts. Note, the bridge must set this flag or
the irq will be unshareable, as things are now.

More work likely is needed, but this is a good checkpoint.

pcic_{get,put}b_io.  There are some pci bridges (the CL-PD6729 and

57462c010c Next step on the road to pci: power taming.
Work through the various power commands and convert them from a "is
this a foo controller or a foo' controller or a foo''' controller" to
a cabability based scheme.  We have bits in the softc that tell us
what kind of power control scheme the controller uses, rather than
relying on being able to enumerate them all.  Cardbus bridges are
numerous, but nearly all implement the i82365sl-DF scheme (well, a few
implement cirrus CL-PD67xx, but those were made by Cirrus Logic!).

Add a pointer back to the softc in each pcic_slot so we can access
these flags.

Add comments that talk about the issues here.  Also note in passing
that there are two differ Vpp schemes in use and that we may need to
adjust the code to deal with both of them.  Note why it usually works
now.

We have 5 power management modes right now: KING, AB, DF, PD and VG.
AB is for the i82365 stpes A, B and C.  DF is for step DF.  PD is the
cirrus logic extensions for 3.3V while VG is the VADEM extensions for
3.3V.  KING is for the IBM KING controller found on some old cards.
# I'm looking for one of those old cards or a laptop that has the KING
# bridge in it.

We have to still cheat and treat the AB parts like the DF parts
because pci isn't here yet.  As far as I can tell, this is harmless
for actual old parts and necessary to work with 3.3V cards in some
laptops.

This almost eliminates all tests for controller in the code.  There
are still a few unrelated to power that need taming as well.

e67316366d Next step towards pcic_pci: the ability to allocate mapped memory in attach.
o Introduce flags word to the softc.  This will be used to control various
  aspects of the driver.  Right now there are two bits defined, PCIC_IO_MAPPED
  and PCIC_MEM_MAPPED.  One for ISA cards that are I/O mapped, the other is
  for PCI cards that are memory mapped.  Only the ISA side is implemented
  with this commit.
o Introduce a pcic_dealloc which will cleanly dealloc resources used.  Right
  now it is only supported when called from probe/attach.
o Keep track of resources allocated in the pcic_softc.
o move pcictimeout_ch to the softc so we can support multiple devices
  in polling mode.
o In ISA probe, set PCIC_IO_MAPPED.
o Introduce and compute the slot mask.  This will be used later when
  we expand the number of slots on ISA from 2 to 4.  In such a case, we
  appear to have to use polling mode otherwise we get two different cards
  trying to drive the same interrupt line.  I don't have hardware to
  test this configuration, so I'll stop here.

aa3a855755 Add back the plain i82365 to the list of bridges that do special
things to get 3.3V.  It appears that some cardbus chipsets have id
registers that say they are C step parts, but they really support the
DF step 3.3V functionality.

# register is really a cirrus logic only register.

08db6b5c8e It turns out that Intel's i82365sl-DF step has the same ID as the VLSI
82C146.  The Intel i82365SL-DF supports 3.3V cards.  The Step A/B/C
parts do not appear to support this.  This is hard to know for sure
since it was deduced from "compatible" parts' data sheets and the
article mentioned below.

Rework the VLSI detection to be a little nicer and not depend on
scanning cards twice.  This would allow bad VLSI cards to coexist with
a good intel card, for example.  We now detect i82365SL-DF cards where
before we'd detect a VLSI.  For the most part, this is good, but we
run a small chance of detecting a single slot 82C146 as a i82365SL-DF.
Since I can't find a datasheet for the 82c146, I don't know if this is
a problem or not.

This work is based on an excellent article, in Japanese, by NAKAGAWA,
Yoshihisa-san that appeared in FreeBSD Press Number 4.  He provided a
patch against PAO3 in his article.  Since the pcic.c code has changed
some since then, I've gone ahead and cleaned up his patch somewhat and
changed how the code detects the buggy '146 cards.

I also removed the comment asking if there were other cards that
matched the 82C146 since we found one and additional information isn't
necessary.

5a695e4878 Separate out isa attachment to its own file. The pci attachment will
soon attach directly to pcic rather than the kludge pci-pcic device we
have now.

In some ways, this is similar to the work PAO3 did to try to support
cardbus bridges.  In some ways different.  This and future commits
will be taking from the spirit of many of those changes.  pcicvar.h is
completely different from the pcicvar.h that appeared in PAO3, but
similar in concept.

07e0ca29b5 Fix the so called "static bug" in polling mode. Some desktop cards
have bad grounding characteristics which allow small static discharges
(or sunspots, we're not 100% sure which) to reach the bridge chip.
This causes the bridge chip to wedge/reset itself.  There's no known
cure short of rebooting.

The bug manifests itself by the STAT_CHG return 0xff when read.  This
is impossible because the upper bits are reserved (and therefore
zero).  In addition, some of the lower bits are one only for memory
cards, which OLDCARD doesn't support, so if they are set, something
seriously foobar'd is going on.

So far we've seen this in exactly one brand of pcmcia <-> isa bridge
which plug and play identifies only as "VIA PCMCIA CARD".  This card
just has buffers on the isa card and the actual bridge chip on the
remote slot, which is connected by long ribbon cables.  We think this
long cable run, coupled with the lack of coupling capacitors is a
major reason why it is so static sensitive while its bretheren aren't.

3ad72a92eb When activating or deactivating a resource, only attempt to deal with
the resource activation if we're dealing with our grandchild.
Otherwise, we run into two problems.  One, if the pccard layer wanted
to allocate and activate something, we'd wind up trying to do the
wrong thing twice: the ivars are wrong and we don't want the bridge to
map the resource to the slot.  If we're more than a grandchild, then
who knows what kind of ivar is present.  In either of these cases, we
just pass it up the food chain.

a66173abd2 Disable the card after sending the removed event up to the pccard
layer.  This fixes an ordering problem that would cause the ISR for
the device to run with now power applied to the device.  Most cards
failed to deal with this gracefully, and thus would hang on card
eject.

The power down event, for those keeping score, is what causes the
interrupt for the card.

Many folks in the Japanese nomads list have reported this, so I'll be
MFCing quickly for their benefit.

36260de0cf Lots of minor cleanup, plus a couple of interesting things.
o Attempt to disable the slot when we detect that there are problems with
  it in our ISR.  This should make polling mode work better for more cards,
  but more work may be needed.  This "disabling" sets the card interrupt
  register to 0.  This worked for me for lots of tests in polling mode.
o Now that I've found datasheets, fix a boatload of magic numbers in the
  source to make it easier to understand.
o Use a table of names rather than a big case statement.
o Cull a few of the "unused" controller types that we map to other times
  that were a vestiage of PAO code that we never merged in the same way.
o Enforce legal IRQs.  You are no longer allowed to try to use IRQs that
  will fail on all known ISA/PCI <-> PCMCIA bridges.  The bridges do not
  have pins for these illegal interrupts, and all of them are listed as
  reserved and/or illegeal in the datasheets depending on which one you
  look at.
o Add comments about how IBM-AT based computers and NEC PC-98 based computers
  map these interrupts and which ones are valid.
o Always clear the bit that steers the management interrupt either to the
  value listed in the PCIC_STAT_INT register.  I've seen this bit get set
  on suspend/resume and after windows boot, and it does't hurt to clear it.
  NOTE: this might mean we can share this interrupt in the future.
