5 * Header file for the GVP Series II SCSI controller for Linux
7 * Written and (C) 1993, Ralf Baechle, see gvp11.c for more info
8 * based on a2091.h (C) 1993 by Hamish Macdonald
12 #include <linux/types.h>
23 * if the transfer address ANDed with this results in a non-zero
24 * result, then we can't use DMA.
