Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+README file for the Linux g_NCR5380 driver.
+(c) 1993 Drew Eckhard
+NCR53c400 extensions (c) 1994,1995,1996 Kevin Lentin
+This file documents the NCR53c400 extensions by Kevin Lentin and some
+enhancements to the NCR5380 core.
+This driver supports both NCR5380 and NCR53c400 cards in port or memory
+mapped modes. Currently this driver can only support one of those mapping
+modes at a time but it does support both of these chips at the same time.
+The next release of this driver will support port & memory mapped cards at
+the same time. It should be able to handle multiple different cards in the
+The drivers/scsi/Makefile has an override in it for the most common
+NCR53c400 card, the Trantor T130B in its default configuration:
+ Port: 0x350
+ IRQ : 5
+The NCR53c400 does not support DMA but it does have Pseudo-DMA which is
+supported by the driver.
+If the default configuration does not work for you, you can use the kernel
+command lines (eg using the lilo append command):
+The driver does not probe for any addresses or ports other than those in
+the OVERRIDE or given to the kernel as above.
+This driver provides some information on what it has detected in
+/proc/scsi/g_NCR5380/x where x is the scsi card number as detected at boot
+time. More info to come in the future.
+When NCR53c400 support is compiled in, BIOS parameters will be returned by
+the driver (the raw 5380 driver does not and I don't plan to fiddle with
+This driver works as a module.
+When included as a module, parameters can be passed on the insmod/modprobe
+ 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
+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.)
