e9e688e243 Add SBP-II target mode driver.
Though this is still incomplete and has some missing features such as
exclusive login and event notification, it may be enough for someone
who wants to play with it.

This driver is supposed to work with firewire(4), targ(4) of CAM(4)
and scsi_target(8) which can be found in /usr/share/example/scsi_target.
This driver doesn't require sbp(4) which implements initiator mode.

Sample configuration:

Kernel: (you can use modules as well)
device	firewire
device	scbus
device	targ
device	sbp_targ

After reboot:
# mdconfig -a -t malloc -s 10m
md0
# scsi_target 0:0:0 /dev/md0
(Assuming sbp_targ0 on scbus0)

You should find the 10MB HDD on FreeBSD/MacOS X/WinXP or whatever connected
to the target using FireWire.

Manpage is not finished yet.

fa4b32fa80 All current uses of pci_set_powerstate are bogus, at least in theory.
However, they are presently necessary due to bigger bogusness in the
pci bus layer not doing the right thing on suspend/resume or on
initial device probe.  This is exactly the sort of thing that the
BURN_BRIDGES option was invented for.  Mark all of them as
BURN_BRIDGES.  As soon as I have the powerstate stuff properly
integrated into the pci bus code, I intend to remove all these
workarounds.

f6b1c44d1f Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma.  At the moment, this is used for the
asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg.  dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.

sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms.  The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.

If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.

* sbp(4) drives exactly 1 GB in size now no longer use extended geometry.
* umass(4) drives exactly 1 GB in size now no longer use extended geometry.

For all other controllers in this commit, this should be a no-op.

77ee030b5f MFp4(simokawa_firewire):
Many internal structure changes for the FireWire driver.

- Compute CRC in CROM parsing.
- Add support for configuration ROM build.
- Simplify dummy buffer handling.
- busdma conversion
- Use swi_taskqueue_giant for -current.  Mark the interrupt routine as MPSAFE.
- AR buffer handling.
	Don't reallocate AR buffer but just recycle it.
	Don't malloc and copy per packet in fwohci_arcv().
	Pass packet to fw_rcv() using iovec.
	Application must prepare receiving buffer in advance.
- Change fw_bind API so that application should pre-allocate xfer structure.
- Add fw_xfer_unload() for recycling struct fw_xfer.
- Add post_busreset hook
- Remove unused 'sub' and 'act_type' in struct fw_xfer.
- Remove npacket from struct fw_bulkxfer.
- Don't call back handlers in fwochi_arcv() if the packet has
	not drained in AT queue
- Make firewire works on big endian platform.
- Use native endian for packet header and remove unnecessary ntohX/htonX.
- Remove FWXFERQ_PACKET mode.  We don't use it anymore.
- Remove unnecessary restriction of FWSTMAXCHUNK.
- Don't set root node for phy config packet if the root node is
	not cycle master capable but set myself for root node.
	We should be the root node after next bus reset.

Prior to rev 1.41, we keep writing the register while bus reset phase.
But in rev 1.41, we ignore successive bus reset events and some chips seem to
clear the register after we write to it.

Improve SBP device probeing:
- Wait 2 sec before issuing LOGIN ORB expecting the reconnection

- Serialize management ORB and scanning LUN by CAM on each target.
	This should fix the problem for devices which have multiple LUNs.
	Test device is donated by: Jaye Mathisen <mrcpu@internetcds.com>
- Freeze SIM queue for 2 sec after BUS RESET.
- Retry with LOGIN rather than RECONNECT after LOGIN is not completed for
	BUS RESET.
- Use appropriate CAM status for BUS RESET and DEVICE RESET.
- Let CAM to scan targets after BUS REST.
- Implement CAM scan target function.
- Keep our own devq freeze count.
- Let CAM to know that SBP does tagged queuing.

These should be merged to RELENG_4 before 4.8-RELEASE.

07159f9c56 Cleanup of the d_mmap_t interface.
- Get rid of the useless atop() / pmap_phys_address() detour.  The
  device mmap handlers must now give back the physical address
  without atop()'ing it.
- Don't borrow the physical address of the mapping in the returned
  int.  Now we properly pass a vm_offset_t * and expect it to be
  filled by the mmap handler when the mapping was successful.  The
  mmap handler must now return 0 when successful, any other value
  is considered as an error.  Previously, returning -1 was the only
  way to fail.  This change thus accidentally fixes some devices
  which were bogusly returning errno constants which would have been
  considered as addresses by the device pager.
- Garbage collect the poorly named pmap_phys_address() now that it's
  no longer used.
- Convert all the d_mmap_t consumers to the new API.

I'm still not sure wheter we need a __FreeBSD_version bump for this,
since and we didn't guarantee API/ABI stability until 5.1-RELEASE.

Some drives seem to be confused by simultaneous probes.

Tested by: marcel

As a side effect, logical units whose lun is greater than 0 might not be
probed correctly if the lun of 0 doesn't exist in the target because
CAM doesn't scan such luns.
I have a SCSI-FireWire bridge which maps SCSI-ID to LUN and it is an
example of such targets.
