I've been quiet lately but I had some time at BSDCAN to cleanup some of
my firewire sbp_targ diffs and would like to get them out for review.
1. I've added a new XPORT_FW type to sys/cam/cam_ccb.h for firewire. I
have added a couple of patches from RELENG_7 to my tree, but they can be
ignored:

2. I've added a new file to sbp_targ(fwcsr.c) that currently only
handles the Busy Timeout register, but will undoubtably handle more in
the future:

3. Finally, the code. I'm attaching a diff, however it's pretty
intrusive so I'm also placing a tar ball of the code on my web server at:
http://www.consultcsg.com/firewire_sbp-targ.tgz so you can review the
entirety of the code at your leisure.
I am still working on the code at this time and will be generating even
more intrusive patches to support SBP-2 and possibly SBP-3 soon-ish.
