29: * TODO : flesh out DMA support, find some one actually using this (I have
30: * a memory mapped Trantor board that works fine)
31: */
32:
33: /*
34: * Options :
35: *
36: * PARITY - enable parity checking. Not supported.
37: *
38: * SCSI2 - enable support for SCSI-II tagged queueing. Untested.
39: *
40: * USLEEP - enable support for devices that don't disconnect. Untested.
41: *
42: * The card is detected and initialized in one of several ways :
43: * 1. With command line overrides - NCR5380=port,irq may be
44: * used on the LILO command line to override the defaults.
45: *
46: * 2. With the GENERIC_NCR5380_OVERRIDE compile time define. This is
47: * specified as an array of address, irq, dma, board tuples. Ie, for
48: * one board at 0x350, IRQ5, no dma, I could say
49: * -DGENERIC_NCR5380_OVERRIDE={{0xcc000, 5, DMA_NONE, BOARD_NCR5380}}
50: *
51: * -1 should be specified for no or DMA interrupt, -2 to autoprobe for an
52: * IRQ line if overridden on the command line.
53: *
54: * 3. When included as a module, with arguments passed on the command line:
55: * ncr_irq=xx the interrupt
56: * ncr_addr=xx the port or base address (for port or memory
57: * mapped, resp.)
58: * ncr_dma=xx the DMA
59: * ncr_5380=1 to set up for a NCR5380 board
60: * ncr_53c400=1 to set up for a NCR53C400 board
61: * e.g.
62: * modprobe g_NCR5380 ncr_irq=5 ncr_addr=0x350 ncr_5380=1
63: * for a port mapped NCR5380 board or
64: * modprobe g_NCR5380 ncr_irq=255 ncr_addr=0xc8000 ncr_53c400=1
65: * for a memory mapped NCR53C400 board with interrupts disabled.
66: *
67: * 255 should be specified for no or DMA interrupt, 254 to autoprobe for an
68: * IRQ line if overridden on the command line.
