* crypto: arm/aes-scalar - unexport en/decryption routinesArd Biesheuvel2019-07-261-3/+0
| | | | | | | | The scalar table based AES routines are not used by other drivers, so let's keep it that way and unexport the symbols. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: aes - rename local routines to prevent future clashesArd Biesheuvel2019-07-261-4/+4
| | | | | | | | | Rename some local AES encrypt/decrypt routines so they don't clash with the names we are about to introduce for the routines exposed by the generic AES library. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: arm/aes - replace scalar AES cipherArd Biesheuvel2017-01-121-0/+74
This replaces the scalar AES cipher that originates in the OpenSSL project with a new implementation that is ~15% (*) faster (on modern cores), and reuses the lookup tables and the key schedule generation routines from the generic C implementation (which is usually compiled in anyway due to networking and other subsystems depending on it). Note that the bit sliced NEON code for AES still depends on the scalar cipher that this patch replaces, so it is not removed entirely yet. * On Cortex-A57, the performance increases from 17.0 to 14.9 cycles per byte for 128-bit keys.
