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