crypto: talitos - Freescale integrated security engine (SEC) driver Add support for the SEC available on a wide range of PowerQUICC devices, e.g. MPC8349E, MPC8548E. This initial version supports authenc(hmac(sha1),cbc(aes)) for use with IPsec. Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
