Patrick Steuer b087dfab4d s390/crypto: add SIMD implementation for ChaCha20 
Add an implementation of the ChaCha20 stream cipher (see e.g. RFC 7539)
that makes use of z13's vector instruction set extension.

The original implementation is by Andy Polyakov which is
adapted for kernel use.

Four to six blocks are processed in parallel resulting in a performance
gain for inputs >= 256 bytes.

chacha20-generic

1 operation in 622 cycles (256 bytes)
1 operation in 2346 cycles (1024 bytes)

chacha20-s390

1 operation in 218 cycles (256 bytes)
1 operation in 647 cycles (1024 bytes)

help
This sets the default maximum request size to perform AES requests
using software instead of the crypto engine. It can be changed by
setting the aes_sw_max_len parameter.
Small blocks are processed faster in software than hardware.
Considering the 256-bit ciphers, software is 2-3 times faster than
qce at 256-bytes, 30% faster at 512, and about even at 768-bytes.
With 128-bit keys, the break-even point would be around 1024-bytes.
The default is set a little lower, to 512 bytes, to balance the
cost in CPU usage. The minimum recommended setting is 16-bytes
(1 AES block), since AES-GCM will fail if you set it lower.
Setting this to zero will send all requests to the hardware.
Note that 192-bit keys are not supported by the hardware and are
always processed by the software fallback, and all DES requests
are done by the hardware.

This driver interfaces with the SafeXcel EIP-97 and EIP-197 cryptographic
engines designed by Inside Secure. It currently accelerates DES, 3DES and
AES block ciphers in ECB and CBC mode, as well as SHA1, SHA224, SHA256,
SHA384 and SHA512 hash algorithms for both basic hash and HMAC.
Additionally, it accelerates combined AES-CBC/HMAC-SHA AEAD operations.

Say 'Y' to enable a driver for the REE interface of the Arm
TrustZone CryptoCell family of processors. Currently the
CryptoCell 713, 703, 712, 710 and 630 are supported.
Choose this if you wish to use hardware acceleration of
cryptographic operations on the system REE.
If unsure say Y.
