38 * TODO : flesh out DMA support, find some one actually using this (I have
39 * a memory mapped Trantor board that works fine)
45 * PARITY - enable parity checking. Not supported.
47 * SCSI2 - enable support for SCSI-II tagged queueing. Untested.
49 * USLEEP - enable support for devices that don't disconnect. Untested.
51 * The card is detected and initialized in one of several ways :
52 * 1. With command line overrides - NCR5380=port,irq may be
53 * used on the LILO command line to override the defaults.
55 * 2. With the GENERIC_NCR5380_OVERRIDE compile time define. This is
56 * specified as an array of address, irq, dma, board tuples. Ie, for
57 * one board at 0x350, IRQ5, no dma, I could say
58 * -DGENERIC_NCR5380_OVERRIDE={{0xcc000, 5, DMA_NONE, BOARD_NCR5380}}
60 * -1 should be specified for no or DMA interrupt, -2 to autoprobe for an
61 * IRQ line if overridden on the command line.
63 * 3. When included as a module, with arguments passed on the command line:
64 * ncr_irq=xx the interrupt
65 * ncr_addr=xx the port or base address (for port or memory
68 * ncr_5380=1 to set up for a NCR5380 board
69 * ncr_53c400=1 to set up for a NCR53C400 board
71 * modprobe g_NCR5380 ncr_irq=5 ncr_addr=0x350 ncr_5380=1
72 * for a port mapped NCR5380 board or
73 * modprobe g_NCR5380 ncr_irq=255 ncr_addr=0xc8000 ncr_53c400=1
74 * for a memory mapped NCR53C400 board with interrupts disabled.
76 * 255 should be specified for no or DMA interrupt, 254 to autoprobe for an
77 * IRQ line if overridden on the command line.
