Say 'Y' to enable a driver for the Arm TrustZone CryptoCell
family of processors. Currently only the CryptoCell 712 REE
is supported.
Say 'Y' to enable a driver for the REE interface of the Arm
TrustZone CryptoCell family of processors. Currently the
CryptoCell 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.
