Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult
to determine what other changes can/should be merged.

No objections from: pfg

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Add support for managing PCI bus numbers. As with BARs and PCI-PCI bridge
I/O windows, the default is to preserve the firmware-assigned resources.
PCI bus numbers are only managed if NEW_PCIB is enabled and the architecture
defines a PCI_RES_BUS resource type.
- Add a helper API to create top-level PCI bus resource managers for each
PCI domain/segment. Host-PCI bridge drivers use this API to allocate
bus numbers from their associated domain.
- Change the PCI bus and CardBus drivers to allocate a bus resource for
their bus number from the parent PCI bridge device.
- Change the PCI-PCI and PCI-CardBus bridge drivers to allocate the
full range of bus numbers from secbus to subbus from their parent bridge.
The drivers also always program their primary bus register. The bridge
drivers also support growing their bus range by extending the bus resource
and updating subbus to match the larger range.
- Add support for managing PCI bus resources to the Host-PCI bridge drivers
used for amd64 and i386 (acpi_pcib, mptable_pcib, legacy_pcib, and qpi_pcib).
- Define a PCI_RES_BUS resource type for amd64 and i386.

Don't call destroy_dev on the alias. This fixes half a dozen PRs I think.

Create a /dev/cardbus%d.cis, to be compatible with older versions of
the software. This is a trivial amount of code to keep wireless
monitoring software working... I plan on removing it in 9.0.

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: go ahead
and set the bits, but we ignore them.

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.

Use PCIR_BARS rather than CARDBUS_BASE0_REG
Style nit.

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...

Use the standard FreeBSD license

MFp4:
u_int*_t -> uint*_t to conform more closely with C99.

Implement PCI_IVAR_ETHADDR. Cardbus has the MAC addr in the CIS,
sometimes, so return it when requested and it does. Also a little
more infrastructure for a few other things.

Add extra set of parens around the barbit macro to make it clear what
we're intending to shift.

Spotted by: flexlint by way of phk (should fix about 40 messages)

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.

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

Non-functional changes to NEWCARD stuff.
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.

(note that not all style violations are fixed in this commit -- those that
aren't will be clobbered by the next commit.)

Initial commit of NEWCARD cardbus side (that actually compiles and works)

Files:
dev/cardbus/cardbus.c
dev/cardbus/cardbusreg.h
dev/cardbus/cardbusvar.h
dev/cardbus/cardbus_cis.c
dev/cardbus/cardbus_cis.h
dev/pccbb/pccbb.c
dev/pccbb/pccbbreg.h
dev/pccbb/pccbbvar.h
dev/pccbb/pccbb_if.m

This should support:
- cardbus controllers:
* TI 113X
* TI 12XX
* TI 14XX
* Ricoh 47X
* Ricoh 46X
* ToPIC 95
* ToPIC 97
* ToPIC 100
* Cirrus Logic CLPD683x
- cardbus cards
* 3c575BT
* 3c575CT
* Xircom X3201 (includes IBM, Xircom and, Intel cards)
[ 3com support already in kernel, Xircom will be committed real soon now]

This doesn't work with 16bit pccards under NEWCARD.

Enable in your config by having "device pccbb" and "device cardbus".
(A "device pccard" will attach a pccard bus, but it means you system have
a high chance of panicing when a 16bit card is inserted)

It should be fairly simple to make a driver attach to cardbus under
NEWCARD -- simply add an entry for attaching to cardbus on a new
DRIVER_MODULE and add new device IDs as necessary. You should also make
sure the card can be detached nicely without the interrupt routine doing
something weird, like going into an infinite loop. Usually that should
entail adding an additional check when a pci register or the bus space is
read to check if it equals 0xffffffff.

Any problems, please let me know.

Raw import of newconfig cardbus code. This is effectively an import,
so the code doesn't compile. I added $FreeBSD$ headers.
