   4 Subject: [PATCH 03/25] crypto: crypto4xx - set CRYPTO_ALG_KERN_DRIVER_ONLY
   5  flag
   6
   7 The security offload function is performed by a cryptographic
   8 engine core attached to the 128-bit PLB (processor local bus)
   9 with builtin DMA and interrupt controllers. This, I think,
  10 satisfies the requirement for the CRYPTO_ALG_KERN_DRIVER_ONLY
  11 flag.
