Subject: [PATCH] MLK-19053 crypto: caam - RNG4 TRNG errata

The TRNG as used in RNG4, used in CAAM has a documentation issue. The
|
|
effect is that it is possible that the entropy used to instantiate the
|
|
DRBG may be old entropy, rather than newly generated entropy. There is
|
|
proper programming guidance, but it is not in the documentation.
