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.

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.
