585b5fa63d crypto: arm/aes - Select SIMD in Kconfig
The skcipher conversion for ARM missed the select on CRYPTO_SIMD,
causing build failures if SIMD was not otherwise enabled.

Fixes: da40e7a4ba ("crypto: aes-ce - Convert to skcipher")
Fixes: 211f41af53 ("crypto: aesbs - Convert to skcipher")

c80ae7ca37 crypto: arm/sha512 - accelerated SHA-512 using ARM generic ASM and NEON
This replaces the SHA-512 NEON module with the faster and more
versatile implementation from the OpenSSL project. It consists
of both a NEON and a generic ASM version of the core SHA-512
transform, where the NEON version reverts to the ASM version
when invoked in non-process context.

This patch is based on the OpenSSL upstream version b1a5d1c65208
of sha512-armv4.pl, which can be found here:

  https://git.openssl.org/gitweb/?p=openssl.git;h=b1a5d1c65208

Performance relative to the generic implementation (measured
using tcrypt.ko mode=306 sec=1 running on a Cortex-A57 under
KVM):

b48321def4 crypto: arm/sha256 - avoid sha256 code on ARMv7-M
The sha256 assembly implementation can deal with all architecture levels
from ARMv4 to ARMv7-A, but not with ARMv7-M. Enabling it in an
ARMv7-M kernel results in this build failure:

arm-linux-gnueabi-ld: error: arch/arm/crypto/sha256_glue.o: Conflicting architecture profiles M/A
arm-linux-gnueabi-ld: failed to merge target specific data of file arch/arm/crypto/sha256_glue.o

This adds a Kconfig dependency to prevent the code from being disabled
for ARMv7-M.

f2f770d74a crypto: arm/sha256 - Add optimized SHA-256/224
Add Andy Polyakov's optimized assembly and NEON implementations for
SHA-256/224.

The sha256-armv4.pl script for generating the assembly code is from
OpenSSL commit 51f8d095562f36cdaa6893597b5c609e943b0565.

Compared to sha256-generic these implementations have the following
tcrypt speed improvements on Motorola Nexus 6 (Snapdragon 805):
