/*
* 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.
