Hello
The main goal of this serie is to add support for TRNG, PRNG and hashes
to the sun8i-ss/sun8i-ce.
The whole serie is tested with CRYPTO_EXTRA_TESTS enabled and loading
tcrypt.
The PRNG and TRNG are tested with rngtest.
Regards
Change since v1:
- removed _crypto_rng_cast patch
Change since v2:
- cleaned unused variables from sun8i-ce-prng
- added some missing memzero_explicit

Instead of using an hardcoded value, let's use a defined value for
SS_START.
