+	This option causes char devices created for FSI devices to be
+	located under a common /dev/fsi/ directory. Set to N unless your
+	userspace has been updated to handle the new location.
+
+	Additionally, it also causes the char device names to be offset
+	by one so that chip 0 will have /dev/scom1 and chip1 /dev/scom2
