HISTORY
     The fwohci device driver first appeared in FreeBSD 5.0.  It was added to
     NetBSD 4.0.

AUTHORS
     The fwohci device driver was written by Katsushi Kobayashi and Hidetoshi
     Shimokawa.  It was added to NetBSD 4.0 by KIYOHARA Takashi.

BUGS
     The driver allows physical access from any node on the bus by default.
     This means that any devices on the bus can read and modify any memory
     space which can be accessed by an IEEE 1394 OHCI chip.  It is allowed
     mostly for sbp(4) devices.  This should be changed to allow it only for
     specific devices.  Anyway, IEEE1394 is a bus and not expected to be con-
     nected with un-trustable devices because a node can monitor all the traf-
     fic.

NetBSD 6.0                       June 18, 2005                      NetBSD 6.0
