2015-04-10crypto: sha512 - implement base layer for SHA-512Ard Biesheuvel1-0/+131
To reduce the number of copies of boilerplate code throughout the tree, this patch implements generic glue for the SHA-512 algorithm. This allows a specific arch or hardware implementation to only implement the special handling that it needs. The users need to supply an implementation of void (sha512_block_fn)(struct sha512_state *sst, u8 const *src, int blocks) and pass it to the SHA-512 base functions. For easy casting between the prototype above and existing block functions that take a 'u64 state[]' as their first argument, the 'state' member of struct sha512_state is moved to the base of the struct.
