Subject: [PATCH 03/13] firewire-sbp-target: Add Kconfig, Makefile and TODO

The FireWire SBP-2 Target is a driver for using an IEEE-1394 connection
as a SCSI transport. This module uses the SCSI Target framework to
expose LUNs to other machines attached to a FireWire bus, in effect
acting as a FireWire hard disk similar to FireWire Target Disk mode on
older Apple computers.
