3  FlashPoint.c -- FlashPoint SCCB Manager for Linux
4
5  This file contains the FlashPoint SCCB Manager from BusLogic's FlashPoint
6  Driver Developer's Kit, with minor modifications by Leonard N. Zubkoff for
7  Linux compatibility.  It was provided by BusLogic in the form of 16 separate
8  source files, which would have unnecessarily cluttered the scsi directory, so
9  the individual files have been combined into this single file.
