This is the "Juju" FireWire stack, a new alternative implementation
designed for robustness and simplicity. You can build either this
stack, or the old stack (the ieee1394 driver, ohci1394 etc.) or both.
Please read http://ieee1394.wiki.kernel.org/index.php/Juju_Migration
before you enable the new stack.

To compile this driver as a module, say M here: the module will be
called firewire-core.

This module functionally replaces ieee1394, raw1394, and video1394.
To access it from application programs, you generally need at least
libraw1394 version 2. IIDC/DCAM applications also need libdc1394
version 2. No libraries are required to access storage devices
through the firewire-sbp2 driver.
