+config RTC_NO_SYNC

+	help
+	  The Real Time Clock is read aligned by default. That means a
+	  series of reads of the RTC are done until it's verified that
+          the RTC's state has just changed.  If you enable this feature,
+          this synchronization will not be performed.  The result is that
+	  the machine will boot up to 1 second faster. 
+
+	  A drawback is that, with this option enabled, your system
+	  clock may drift from the correct value over the course
+	  of several boot cycles (under certain circumstances).
+
+	  If unsure, say N.
