  FlashPoint.c -- FlashPoint SCCB Manager for Linux

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

 *              (1) Start data transfer by calling HOST_DATA_XFER_START
 *              function.  Once data transfer is started, (2) Depends
 *              on the type of data transfer mode Scatter/Gather mode
 *              or NON Scatter/Gather mode.  In NON Scatter/Gather mode,
 *              this routine checks Sccb_MGRFlag (F_HOST_XFER_ACT bit) for
 *              data transfer done.  In Scatter/Gather mode, this routine
 *              checks bus master command complete and dual rank busy
 *              bit to keep chaining SC transfer command.  Similarly,
 *              in Scatter/Gather mode, it checks Sccb_MGRFlag
 *              (F_HOST_XFER_ACT bit) for data transfer done.
