/*
 * 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.  Ie, for
 *     one board at 0x350, IRQ5, no dma, I could say  
 *     -DGENERIC_NCR5380_OVERRIDE={{0xcc000, 5, DMA_NONE, BOARD_NCR5380}}
 * 
 * -1 should be specified for no or DMA interrupt, -2 to autoprobe for an 
 * 	IRQ line if overridden on the command line.
 *
 * 3.  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.
