10 Module (CAAM), also known as the SEC version 4 (SEC4). The driver uses
11 Job Ring as interface to communicate with CAAM.

66 bool "Enable Random Number Generator support"
70 Enable support for the hardware based random number generator
71 module of the CAAM. The random data is fetched from the DRGB
72 using the prediction resistance flag which means the DRGB is
73 reseeded from the TRNG every time random data is generated.
78 bool "Enable Random Number Generator support"
82 Enable support for the hardware based random number generator
83 module of the DCP. It uses the True Random Number Generator (TRNG)
84 and a Pseudo-Random Number Generator (PRNG) to achieve a true
85 randomness and cryptographic strength.
