+	  When this flag is yes, the driver will not use interrupts to
+	  determine when the hardware has completed a task, but instead
+	  will hold onto the CPU and continually poll the hardware until

+    help
+        To avoid infinite polling, a timeout is provided. Should the
+        timeout be reached, a fault is reported, indicating there must
+        be something wrong with SAHARA, and SAHARA is reset. The loop
+        will exit after the given number of iterations.
