Subject: kernel: build arm/neon-optimized sha1/512 modules
X-Git-Tag: v21.02.0-rc1~3673
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=e889489bedfd2830411bd0cf6564b8272aa9c254

kernel: build arm/neon-optimized sha1/512 modules

This builds the regular arm and arm-neon asm optmized modules for sha1
and sha512, for targets that set CONFIG_ARM_CRYPTO.

On ip40xx, the arm-asm version of sha1 improves performance by 5% over
the generic C implementation; sha1-neon is 25% faster than generic,
and sha512-neon, 259%.
