a63eba960f When we can't parse the CIS, note with a warning that the bogus CIS
was ignored, rather than freaking out.  In the past, it wasn't possible
to not parse the CIS, so this changes no behavior.

5aa58b3e8f Make the 'pci_devclass' pointer variable private (drivers really shouldn't
share devclass pointers, a mistake I've encouraged in the past) and
move the declaration of the pci_driver kobj class from cardbus.c to
pci_private.h so that other drivers can inherit from pci_driver.

bee89c7386 Use the child to allocate the resource rather than bridge, since we're
allocating a resource that's in the card itself.

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
# the BARs.  Don't know yet if this fixes the amd64 issues reported.

086745614c When in rev. 1.47 cardbus_alloc_resources() function was moved from
cardbus_cis.c to this file, some code was not merged and thus resource
list entries were invalid. They didn't have a resources attached to
them.
  However, the problem was masked for some time later, because newer
resources list entries were added to the head of the list, and
resource_list_find() always returned the first matching resource list
entry. Usually the underlying driver allocated a valid resource and
added it to the head of the list, and invalid one wasn't used.
  In rev. 1.174 of subr_bus.c the sorting of resource list entries was
reversed demasking the problem in cardbus_alloc_resources().
  This commit fixes the problem returning back some code from
cardbus_cis.c, pre-1.49 revisions.

36fed96550 Use STAILQ in preference to SLIST for the resources. Insert new resources
last in the list rather than first.

This makes the resouces print in the 4.x order rather than the 5.x order
(eg fdc0 at 0x3f0-0x3f5,0x3f7 is 4.x, but 0x3f7,0x3f0-0x3f5 is 5.x).  This
also means that the pci code will once again print the resources in BAR
ascending order.

0f675788ff Revert changes of 1.49. Lots-a-people broke with it, for reasons
unknown (since my sony vaio didn't :-(.

Instead, fix the problem described by 1.49 in a different way: just
add the two calls I'd hoped I'd avoid in 1.49 by doing the (wrong)
gymnastics there.  While 1.49 is a good direction to go in, each step
of the way should work :-(.

af5e97c122 There were two calls to cardbus_do_cis when cardbus_do_cis changed,
yet I only changed one of them.  So when we loaded drivers, we'd fail
to allocate resources correct.

This pointed out that we were doing the wrong thing when we failed to
attach a child.  We released all the resources and almost deleted the
child.  Instead, we should keep the resources allocated so when/if a
driver is loaded, we can go w/o having to allocate them.  We use
pci_cfg_save/restore to restore the BARs with these resources.

This seems to fix the problems that we were seeing that I thought
might have magically gone away in the last revision of cardbus.c (but
really didn't).

440b5ade31 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_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...

3920999db7 Add a new PCI interface method, assign_interrupt, to determine the
interrupt to be used for a device. This is intended solely for internal
use of PCI bus implementations, and exists so that PCI bus drivers
implementing special interrupt assignment methods which require
additional work at the bus level to work right can be easily derived
from the generic driver (or any other one) without resorting to hacks.

It will be used in the sparc64 ofw_pcibus driver, which will be
committed shortly.

Make use of this method in the generic implementation, and add it to
the method table of bus drivers derived from the PCI one.

f9aedaa4ba 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.

Remove some fairly useless debug writes.

This finishes the work to move as much cardbus code as possible into

releasing resources on detach.
