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!

FlashPoint.c -- FlashPoint SCCB Manager for Linux
|
|
|
|
This file contains the FlashPoint SCCB Manager from BusLogic's FlashPoint
|
|
Driver Developer's Kit, with minor modifications by Leonard N. Zubkoff for
|
|
Linux compatibility. It was provided by BusLogic in the form of 16 separate
|
|
source files, which would have unnecessarily cluttered the scsi directory, so
|
|
the individual files have been combined into this single file.
