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!

+The sym53c500_cs driver originated as an add-on to David Hinds' pcmcia-cs
+package, and was written by Tom Corner (tcorner@via.at). A rewrite was
+long overdue, and the current version addresses the following concerns:
+
+ (1) extensive kernel changes between 2.4 and 2.6.
+ (2) deprecated PCMCIA support outside the kernel.
+
+All the USE_BIOS code has been ripped out. It was never used, and could
+not have worked anyway. The USE_DMA code is likewise gone. Many thanks
+to YOKOTA Hiroshi (nsp_cs driver) and David Hinds (qlogic_cs driver) for
+the code fragments I shamelessly adapted for this work. Thanks also to
+Christoph Hellwig for his patient tutelage while I stumbled about.
+
+The Symbios Logic 53c500 chip was used in the "newer" (circa 1997) version
+of the New Media Bus Toaster PCMCIA SCSI controller. Presumably there are
+other products using this chip, but I've never laid eyes (much less hands)
+on one.
+
+Through the years, there have been a number of downloads of the pcmcia-cs
+version of this driver, and I guess it worked for those users. It worked
+for Tom Corner, and it works for me. Your mileage will probably vary.
