For timeout values adopt unsigned long, which is the type of jiffies etc. For chip register values and bit masks pass u8, which is the return type of readb, inb etc. For device register offsets adopt unsigned int, as it is suitable for adding to base addresses. Pass the NCR5380_hostdata pointer to the board-specific routines instead of the Scsi_Host pointer. The board-specific code is concerned with hardware and not with SCSI protocol or the mid-layer.
