| This option enables the 54L CRACEN based entropy driver, based on the nrfx CRACEN CTR_DRBG |
| random driver. |
| Notes: This driver is only compatible with 54L devices, and may only be used from one processor |
| core. This driver cannot be used in conjunction with the nRF security PSA solution, as both |
| would attempt to use the CRACEN HW exclusively; When that is enabled, the PSA crypto entropy |
| driver should be selected instead. |
