24 * TODO : flesh out DMA support, find some one actually using this (I have
25 * a memory mapped Trantor board that works fine)

28 /*
29 * The card is detected and initialized in one of several ways :
30 * 1. With command line overrides - NCR5380=port,irq may be
31 * used on the LILO command line to override the defaults.
32 *
33 * 2. With the GENERIC_NCR5380_OVERRIDE compile time define. This is
34 * specified as an array of address, irq, dma, board tuples. Ie, for
35 * one board at 0x350, IRQ5, no dma, I could say
36 * -DGENERIC_NCR5380_OVERRIDE={{0xcc000, 5, DMA_NONE, BOARD_NCR5380}}
37 *
38 * -1 should be specified for no or DMA interrupt, -2 to autoprobe for an
39 * IRQ line if overridden on the command line.
40 *
41 * 3. When included as a module, with arguments passed on the command line:
42 * ncr_irq=xx the interrupt
43 * ncr_addr=xx the port or base address (for port or memory
44 * mapped, resp.)
45 * ncr_dma=xx the DMA
46 * ncr_5380=1 to set up for a NCR5380 board
47 * ncr_53c400=1 to set up for a NCR53C400 board
48 * e.g.
49 * modprobe g_NCR5380 ncr_irq=5 ncr_addr=0x350 ncr_5380=1
50 * for a port mapped NCR5380 board or
51 * modprobe g_NCR5380 ncr_irq=255 ncr_addr=0xc8000 ncr_53c400=1
52 * for a memory mapped NCR53C400 board with interrupts disabled.
53 *
54 * 255 should be specified for no or DMA interrupt, 254 to autoprobe for an
55 * IRQ line if overridden on the command line.
