- Generator available in Arm TrustZone CryptoCell.
-
- To compile this driver as a module, choose M here: the module
+ 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
