2015-05-07crypto: arm64/sha2-ce - prevent asm code finalization in final() pathArd Biesheuvel1-0/+3
Ensure that the asm code finalization path is not triggered when invoked via final(), since it already takes care of that itself. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-04-10crypto: arm64/sha2-ce - move SHA-224/256 ARMv8 implementation to base layerArd Biesheuvel1-177/+50
This removes all the boilerplate from the existing implementation, and replaces it with calls into the base layer. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2014-08-26arm64/crypto: remove redundant update of dataColin Ian King1-1/+0
Originally found by cppcheck: [arch/arm64/crypto/sha2-ce-glue.c:153]: (warning) Assignment of function parameter has no effect outside the function. Did you forget dereferencing it? Updating data by blocks * SHA256_BLOCK_SIZE at the end of sha2_finup is redundant code and can be removed.
