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.

- Improve self id handling

Tested on: i386, sparc64 and i386 with forced bounce buffer

73aa55ba0a - The payload of Write Request Quad and Read Response Quad must be
network byte order.
- Set ATRetries register after each bus reset because the value is 'undef'
	in OHCI spec.

3b79dd164b - improve timeout handling in fwmem.c

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

864d7e72b8 - Detect split transcation timeout.
* implement watchdog timer.
	* check all standing transactions in firewire_xfer_timeout().
- Add firewire_xferq_drain() for fw_busreset().
- Add/improve some debug messages.
- Call fw_xfer_done() if retry handler is NULL.

- fix typo
- don't need to check receive buffer.
- don't forget to free xfer on errer.

48249fe0c8 - Take malloc type as an argument in fw_xfer_alloc().
- Fix overwrite problem of freed buffers. It was rare but could happen
	when fwohci_arcv() is called before fwohci_txd() is called for
	the transcation.
- Drain AT queues and pend AR queues on SID receive rather than BUS reset to
	make sure DMA actually stops.
- Do agent reset in sbp_timeout().

This should fix the IR(and maybe IT) problem when

	fw_noderesolve_nodeid().
