-Subject: [PATCH] MLK-9769-8 crypto: caam - add a test for the RNG
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Freescale's CAAM includes a Random Number Generator.  This change adds
-a kernel configuration option to test the RNG's capabilities via the
-hw_random framework.
