Hi Everyone,

We added Andy Polyakov's ARMv7 AES implementation using ASM. It is the same 
implementation he provided to OpenSSL. Also see 
https://github.com/weidai11/cryptopp/commit/3ff7d7f0286a .

Andy dual licenses his implementations. We added Andy's work under his BSD 
license. It is permissive and should not cause trouble for closed source 
projects.

If CRYPTOGAMS_ARM_AES is enabled in config.h then Andy's implementation is 
used. Otherwise the ARMv7 asm is disabled. You can remove the define in 
config.h and delete the files aes-armv4.h and aes-armv4.S and things will 
continue to work as expected.

The benchmark numbers are very good. Our C/C++ AES-128/CTR was running at 
about 65 cpb. Andy's code runs around 41 cpb. Testing was carried out on a 
low-end BananaPi dev-board @950 MHz.

Also see https://wiki.openssl.org/index.php/Cryptogams_AES on the OpenSSL 
wiki if you are interested in the integration details.

Jeff
