This adds ARMv8 implementations of AES in ECB, CBC, CTR and XTS modes, both for ARMv8 with Crypto Extensions and for plain ARMv8 NEON. The Crypto Extensions version can only run on ARMv8 implementations that have support for these optional extensions. The plain NEON version is a table based yet time invariant implementation. All S-box substitutions are performed in parallel, leveraging the wide range of ARMv8's tbl/tbx instructions, and the huge NEON register file, which can comfortably hold the entire S-box and still have room to spare for doing the actual computations. The key expansion routines were borrowed from aes_generic. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Acked-by: Herbert Xu <herbert@gondor.apana.org.au>
