2 * sym53c500_cs.c Bob Tracy (rct@frus.com)
4 * A rewrite of the pcmcia-cs add-on driver for newer (circa 1997)
5 * New Media Bus Toaster PCMCIA SCSI cards using the Symbios Logic
6 * 53c500 controller: intended for use with 2.6 and later kernels.
7 * The pcmcia-cs add-on version of this driver is not supported
8 * beyond 2.4. It consisted of three files with history/copyright
