CC310 entropy driver

You can use the CC3xx entropy driver (entropy_cc310) to generate random data using the Arm CryptoCell CC310 hardware. This hardware is available on the nRF52840 and nRF9160 devices.

When used on nRF52840, the entropy_cc3xx driver gathers entropy by using the CC310 hardware through the nrf_cc3xx_platform library.

When used on nRF9160, the driver behavior depends on whether it is used in a secure or non-secure application:

When used on nRF5340, the driver behavior depends on whether it is used in a secure or non-secure application:
