Help text

Say 'Y' to enable the True Random Number Generator driver for the Arm TrustZone CryptoCell family of processors. Currently the CryptoCell 713 and 703 are supported. The driver is supported only in SoC where Trusted Execution Environment is not used. Choose 'M' to compile this driver as a module. The module will be called cctrng. If unsure, say 'N'.
