This patch adds ARM NEON assembly implementation of SHA-512 and SHA-384 algorithms. tcrypt benchmark results on Cortex-A8, sha512-generic vs sha512-neon-asm: block-size bytes/update old-vs-new 16 16 2.99x 64 16 2.67x 64 64 3.00x 256 16 2.64x 256 64 3.06x 256 256 3.33x 1024 16 2.53x 1024 256 3.39x 1024 1024 3.52x 2048 16 2.50x 2048 256 3.41x 2048 1024 3.54x 2048 2048 3.57x 4096 16 2.49x 4096 256 3.42x 4096 1024 3.56x 4096 4096 3.59x 8192 16 2.48x 8192 256 3.42x 8192 1024 3.56x 8192 4096 3.60x 8192 8192 3.60x Acked-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Tested-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
