CONFIG_ENTROPY_CC3XX

Arm CC3XX RNG driver for Nordic devices

Type: bool

Help

This option enables the Arm CC3xx RNG devices in nRF52840, nRF5340, and nRF9160
devices. This is dependent on CC3xx being enabled in nrf_security.
This is required for TF-M builds using NORDIC_SECURITY_BACKEND.

Direct dependencies

(CRYPTOCELL_USABLE || SPM || BUILD_WITH_TFM) && ENTROPY_GENERATOR

(Includes any dependencies from ifs and menus.)
