Hello Michael, when typing CAAM into Google I got a lot of answers but "Cryptographic Accelerator and Assurance Module" was not under the first 50 hits. If this is a hardware RNG I think we should put this into the text. So how about: "Enable support the hardware random number generator of Freescale SOCs using the Cryptographic Accelerator and Assurance Module (CAAM)." Best regards Heinrich
