Currently it is possible to select HW_RANDOM as a module and have hifn795x built-in. This causes a build problem because hifn795x will then call hwrng_register which isn't built-in. This patch introduces a new config option to control the hifn795x RNG which lets us avoid this problem. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Some VIA processors come with an integrated crypto engine
|
|
(so called VIA PadLock ACE, Advanced Cryptography Engine)
|
|
that provides instructions for very fast cryptographic
|
|
operations with supported algorithms.
|
|
|
|
The instructions are used only when the CPU supports them.
|
|
Otherwise software encryption is used.
