Documentation for am335x Hardware Crypto

I saw a topic posted about the BBB’s hardware random number generator and crypto accelerators. I think it might be fun to develop a driver for the TRNG for the Minix operating system. However, I can’t find any documentation about the crypto stuff for the am335x. I got the latest TRM, all 4737 pages, and can’t find anything on it in there. I looked at http://ti.com/am3359 but I don’t see anything obvious in the ‘Technical Documents’ section. “Crypto Hardware Accelerators (AES, SHA, PKA, RNG)” is on the feature list on TI’s website. Anyone know where I can find the docs?

Thanks,
Thomas

US gov restricts general release of certain crypto documentation due to export controls. One suggestion is to look at the Linux kernel driver code that ships with the AM335x SDK:

/ti-sdk-am335x-evm-06.00.00.00/board-support/linux-3.2.0-psp04.06.00.11/drivers/char/hw_random/omap4-rng.c
