Register the random number generator with the rng subsystem in u-boot. This way it can be used by EFI as well as for the 'rng' command.

Enable support for the random number generator module of the CAAM.
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
