Untested. * * The card is detected and initialized in one of several ways : * 1. With command line overrides - NCR5380=port,irq may be * used on the LILO command line to override the defaults. * * 2. With the GENERIC_NCR5380_OVERRIDE compile time define. This is * specified as an array of address, irq, dma, board tuples.

When included as a module, with arguments passed on the command line: * ncr_irq=xx the interrupt * ncr_addr=xx the port or base address (for port or memory * mapped, resp.) * ncr_dma=xx the DMA * ncr_5380=1 to set up for a NCR5380 board * ncr_53c400=1 to set up for a NCR53C400 board * e.g. * modprobe g_NCR5380 ncr_irq=5 ncr_addr=0x350 ncr_5380=1 * for a port mapped NCR5380 board or * modprobe g_NCR5380 ncr_irq=255 ncr_addr=0xc8000 ncr_53c400=1 * for a memory mapped NCR53C400 board with interrupts disabled. * * 255 should be specified for no or DMA interrupt, 254 to autoprobe for an * IRQ line if overridden on the command line. * */ /* * $Log: generic_NCR5380.c,v $ */ /* settings for DTC3181E card with only Mustek scanner attached */ #define USLEEP #define USLEEP_POLL 1 #define USLEEP_SLEEP 20 #define USLEEP_WAITLONG 500 #define AUTOPROBE_IRQ #define AUTOSENSE #include <linux/config.h> #ifdef CONFIG_SCSI_GENERIC_NCR53C400 #define NCR53C400_PSEUDO_DMA 1 #define PSEUDO_DMA #define NCR53C400 #define NCR5380_STATS #undef NCR5380_STAT_LIMIT #endif #include <asm/system.h> #include <asm/io.h> #include <linux/signal.h> #include <linux/sched.h> #include <linux/blkdev.h> #include "scsi.h" #include "hosts.h" #include "g_NCR5380.h" #include "NCR5380.h" #include <linux/stat.h> #include <linux/init.h> #include <linux/ioport.h> #include <linux/isapnp.h> #include <linux/delay.h> #include <linux/interrupt.h> #define NCR_NOT_SET 0 static int ncr_irq = NCR_NOT_SET; static int ncr_dma = NCR_NOT_SET; static int ncr_addr = NCR_NOT_SET; static int ncr_5380 = NCR_NOT_SET; static int ncr_53c400 = NCR_NOT_SET; static int ncr_53c400a = NCR_NOT_SET; static int dtc_3181e = NCR_NOT_SET; static struct override { NCR5380_implementation_fields; int irq; int dma; int board; /* Use NCR53c400, Ricoh, etc. extensions ? */ } overrides #ifdef GENERIC_NCR5380_OVERRIDE [] __initdata = GENERIC_NCR5380_OVERRIDE; #else [1] __initdata = { { 0,},}; #endif #define NO_OVERRIDES (sizeof(overrides) / sizeof(struct override)) #ifndef MODULE /** * internal_setup - handle lilo command string override * @board: BOARD_* identifier for the board * @str: unused * @ints: numeric parameters * * Do LILO command line initialization of the overrides array.
