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.
