It appears that these crypto_ wrappers were added so there's "actual" referenceable functions for these structs. Did this actually compile? Thanks,

crypto_sha256_init() and sha256_base_init() are the same repeated implementations, remove the crypto_sha256_init() in generic implementation, sha224 is the same process.
