ebc58977d3 Ignore the 'must allocate below 1MB' flag for the TPL_BAR_REG. It is
set on realtek cards, but they work without it (and don't work with
it).  The standard seems to imply that this is just a hint anyway, so
this should be harmless.  It doesn't appear to be set on any other
cardbus cards that I have (or have seen).

This should make the rl based CardBus cards work again.  I've been
running it for about a month now.

e9ebebfd2b Move the resource handling down into the pci bus as well.
Minor CIS resource allocation code cleanup
Remove some fairly useless debug writes.

This finishes the work to move as much cardbus code as possible into
pci.  We wind up removing 800-odd lines from cardbus.c: we go from
1285 to 400 lines.

0b8c31403a Sanity check the BAR length reported by the CIS with the BAR length that
is encoded in the PCI BAR.  The latter is more reliable.

This allows the sio/modem function of the Xircom RealPort ethernet+modem
card to work.  Note that there still seem to be issues with sio_pci not
releasing resources on detach.

ef91f3388a Checkpoint a work in progress:
o Use the common pci_* routines in preference to the copied and hacked
  routines from an ancient pci.c.

This saves 509 lines in cardbus.c.  More savings to follow when I
convert the resource code over.  In the past when I've done this the
resource code conversion breaks cardbus in subtle ways so I'm doing a
1/2 way checkpoint this time.  cardbus still works for me the same as
it did before.

It also looks like cardbus devices now show up as pci bus devices to
pciconf -l, but maybe that was happening before.

Inspired by a patch from Justin Gibbs many moons ago.  When he
finishes his kobj multiple inheritance work, we can transition the
finished version of this work to that fairly easily.

Kill the slightly bogus #define for DECODE_PROTOTYPE
	Be less verbose.  Hide most (all I hope) of the CIS
	parsing behind cardbus_debug_cis (which is set with
	hw.cardbus.debug_cis=1).

	This doesn't fix problems with parsing, but should make cardbus
	less chatty.  There appears to be some issues still with the
	parsing of the CIS, but this won't fix them.

Second part of the kldload patches for cardbus.  This makes
	kldload of a driver for a device that's inserted now appears
	to work.  To make it work, we only do a power cycle of the card
	if there's no children drivers attached.

	This likely is papering over bogosities in the power system.  The
	power sequence needs to be re-written, so I'll not worry about
	the papering over until the re-write.

87416e10ed When parsing the CIS, if a BAR tuple is encountered, enable the corresponding
bit in the PCI command register for the device.  Otherwise, device drivers
that look at this register to see which types of BARs are usable will think
that none of them are.
This allows my Adaptec 1480A cardbus card to finally work.

f7540bad93 o Add routines to return the location and pnpinfo for this card.
Note, we return the PCI pnp info, but in fact that's wrong to do
  since that data is not defined for CardBus cards.  CardBus says that
  these registers are undefined and one should use the CIS to do
  device matching.  To date, all CardBus cards have had these
  registered defined, no doubt because they are using common silicon
  to produce both the PCI cards and the CardBus cards.  However, it isn't
  any worse than the rest of the system, so just note it in passing and
  move on.
o Also sort prototypes while I'm here.

08e793ff15 Use the pci.c code wherever possible, rather than copying all the pci
code into cardbus and s/pci/cardbus.  This exposes a few pci_*
functions that are now static.

This work is similar to work Justin posted to the mobile list about a
year or two ago, which I have neglected since then.

This is a subset of his current work with the multiple inheritance
newbus architecutre.  When completed, that will eliminate the need for
pci/pci_private.h.

Similar work is needed for the cardbus_cis and pccard_cis code as well.

c07859c916 Part two of this NEWCARD update:
Briefly, the significant changes include:
 * Way better resource management in pccbb, pccard and cardbus.
 * pccard hot-removal now appears to work.
 * support pre-fetchable memory in cardbus.
 * update cardbus to support new pci bus interface functions.
 * Fix CIS reading to no longer use rman_get_virtual().

What's not there, but in the works:
 * pccard needs to do interrupt properly and not read the ISR on single
   function cards.
 * real resource management for pccard
 * a complete implementation of CIS parsing
 * need to look into how to correctly use mutex in pccbb

This is the first part of a two-part update to NEWCARD.  Changes in this
commit are non-functional, and includes the following:
 * indentation and other changes to meet style(9).
 * other minor style consistancy changes
 * addition of comments
 * renaming of device_t variables to be consistant across all of NEWCARD.

 aren't will be clobbered by the next commit.)
