+          This driver allows other kernel drivers access to the
+          contents of the restricted access region control registers.
+
+          The restricted access region control registers
+          (rar_registers) are used to pass address and
+          locking information on restricted access regions
+          to other drivers that use restricted access regions.
+
+          The restricted access regions are regions of memory
+          on the Intel MID Platform that are not accessible to
+          the x86 processor, but are accessible to dedicated
+          processors on board peripheral devices.
+
+          The purpose of the restricted access regions is to
+          protect sensitive data from compromise by unauthorized
+          programs running on the x86 processor.
