* linux/drivers/message/fusion/mptscsih.c
- * High performance SCSI / Fibre Channel SCSI Host device driver.
- * For use with PCI chip/adapter(s):
- * LSIFC9xx/LSI409xx Fibre Channel
+ * For use with LSI Logic PCI chip/adapter(s)
* running LSI Logic Fusion MPT (Message Passing Technology) firmware.
*
- * Credits:
- * This driver would not exist if not for Alan Cox's development
- * of the linux i2o driver.
- *
- * A special thanks to Pamela Delaney (LSI Logic) for tons of work
- * and countless enhancements while adding support for the 1030
- * chip family. Pam has been instrumental in the development of
- * of the 2.xx.xx series fusion drivers, and her contributions are
- * far too numerous to hope to list in one place.
- *
- * A huge debt of gratitude is owed to David S. Miller (DaveM)
- * for fixing much of the stupid and broken stuff in the early
- * driver while porting to sparc64 platform. THANK YOU!
