Fix an error case I missed in the previous change so that the CIS resource
is fully cleaned up if we fail to find the CIS in the devices ROM.

Delete the CIS resource after releasing it. This is needed when the CIS is
stored in a BAR since the CIS BAR is mapped before the PCI bus driver
enumerates all the BARs. Without this change, the PCI bus driver would
attempt to initialize a BAR that was already allocated resulting in a panic.

Teach the PCI bus driver to handle PCIR_BIOS BARs properly and remove special
handling for the PCIR_BIOS decoding enable bit from the cardbus driver.
The PCIR_BIOS BAR does include type bits like other BARs. Instead, it is
always a 32-bit non-prefetchable memory BAR where the low bit is used as a
flag to enable decoding.

Use bus_*() rather than bus_space_*().

Minorly improved debugging. Use the DEVPRINTF macro and report the
offset for memory when mapping in the CIS.

Overhaul of CIS parsing, next step: keep a cached copy of the CIS,
read before we configure the card, so we can implement
/dev/cardbus*.cis. Also, do this on a per-child basis, so we now have
a different name than before. I think i'll have to fix that for some
legacy tools to keep working.

I can now do a dumpcis on my running atheros card and have it still work!

First step in cleaning up CIS parsing and /dev/cardbus*.cis: remove
redundant malloc/free. Add comments about how this should really be
done. Fix an overly verbose comment about under 1MB mapping:

and set the bits, but we ignore them.

This should help everybody trying to run dumpcis on atheros wireless
card as well.

gcc 4.2 thinks that tupleid is uninitialized. Or might be used
uninitialized. It gets passed into other routines that initialize
it... Cope by initializing.

Change PCIM_CIS_ASI_TUPLE to _CONFIG.
Add PCI_MAX_BAR_0
minor style nit.
Add PCIM_CIS_CONFIG_MASK

Minor cleanup of CIS parsing.

Better error message when the CIS is a non-standards conforming '0'.

Remove more now-redundant resource_list_add, and now-redunant code
that lives in the pci layer.

# This fixes the atheros card that I have which had its CIS in one of

Minor style(9) hacking, plus use a macro in place of (struct resource *)~0UL
(what the heck does that mean?).

Fixing build bustage.

The RID2BAR macro returns a number, not a bitmask. Fix this.

Retire BARBIT in favor of new PCI_RID2BAR.

Implement /dev/cardbus%d.cis, same thing as /dev/pccard%d.cis. There
are some rough edges with this still, but it seems to work well enough
to commit.

Eliminate even more duplication, and move some definitions into pcireg.h

Simplify code a little, prefer PCI?_FOO registers where possible.

Be more verbose on errors with CIS reading. This should be a noop, but
appears to fix the ath problem that had been reported. I don't see how
it can, so there's likely some other hidden bug.

Move resource allocation routines from cardbus_cis.c to cardbus.c.
They have nothing at all to do with CIS parsing.

Remove some unused funce parsing: nothing used the results.

Use more of pccard_ci

Use more of pccard_cis.h's deifnitions for the cardbus specific cis
parsing we do. More work is needed in this area.

This reduces the size of the cardbus module by 380 bytes or so...
