Jussi Kivilinna	604682551a	ARM: 8119/1: crypto: sha1: add ARM NEON implementation ... This patch adds ARM NEON assembly implementation of SHA-1 algorithm. tcrypt benchmark results on Cortex-A8, sha1-arm-asm vs sha1-neon-asm: block-size bytes/update old-vs-new 16 16 1.04x 64 16 1.02x 64 64 1.05x 256 16 1.03x 256 64 1.04x 256 256 1.30x 1024 16 1.03x 1024 256 1.36x 1024 1024 1.52x 2048 16 1.03x 2048 256 1.39x 2048 1024 1.55x 2048 2048 1.59x 4096 16 1.03x 4096 256 1.40x 4096 1024 1.57x 4096 4096 1.62x 8192 16 1.03x 8192 256 1.40x 8192 1024 1.58x 8192 4096 1.63x 8192 8192 1.63x 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>	2014-08-02 08:51:47 +01:00
Jussi Kivilinna	1f8673d31a	ARM: 8118/1: crypto: sha1/make use of common SHA-1 structures ... Common SHA-1 structures are defined in <crypto/sha.h> for code sharing. This patch changes SHA-1/ARM glue code to use these structures.
