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.

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 :-(.
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).

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...
The hack for setting the bus has been moved down into the cbb driver.
I've been running without this hack in my tree for so long I had
forgotten that I'd removed it :-). Please let me know if this causes
difficulty for your laptop.
o minor optimization of cardbus_cis processing. Remove a bunch of generic

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.

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.

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.

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.
pci busses implement this.
Also minor comment smithing in cardbus. Fix copyright to this year

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.

attached devices because most drivers assume that one cannot
