scsi: g_NCR5380: Stop using scsi_module.c
Browse files Browse the repository at this point in the history
Convert g_NCR5380 to use scsi_add_host instead of scsi_module.c Use
pnp_driver and isa_driver to manage cards.

In order to support multiple cards, new module parameter format is
introduced. The old parameters are kept for compatibility.

This driver works as a module.
When included as a module, parameters can be passed on the insmod/modprobe
command line:
irq=xx[,...] the interrupt(s)
base=xx[,...] the port or base address(es) (for port or memory mapped, resp.)
card=xx[,...] card type(s):
0 = NCR5380,
1 = NCR53C400,
2 = NCR53C400A,
3 = Domex Technology Corp 3181E (DTC3181E)
4 = Hewlett Packard C2502

These old-style parameters can support only one card:
ncr_irq=xx the interrupt
ncr_addr=xx the port or base address (for port or memory
mapped, resp.)
