+ * TODO : flesh out DMA support, find some one actually using this (I have
+ * a memory mapped Trantor board that works fine)
+ */
+
+/*
+ * Options :
+ *
+ * PARITY - enable parity checking. Not supported.
+ *
+ * SCSI2 - enable support for SCSI-II tagged queueing. Untested.
+ *
+ * USLEEP - enable support for devices that don't disconnect. 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. 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.
