* imx: Add fsl_sec driver for RNG and identity This fsl_sec driver is ported from the PPA implementation by NXP. Temporarily included in OP-TEE to provide hardware RNG and OTPMK derrived identity until a more complete CAAM implementation is ported. To enable the fsl_sec driver you must set the following configs: CFG_FSL_SEC=y CFG_WITH_SOFTWARE_PRNG=n The RNG calls the CAAM to fill a 256 byte buffer, then iterates through the buffer to return bytes to callers until it exhausts its pool of random numbers, at which point it will call the CAAM again. This is to reduce the performance cost of RNG reads since 16 byte buffers are requested frequently during RPMB initialization. The identity derrivation sets the key source to OTPMK and rolls forward the PRIBLOB to 11 normal mode. This ensures that the identity derived for RPMB is identical between booting from Cyres SPL and non-Cyres SPL. If the device isn't in a secure/trusted state it will return a failure on device identity so that a false RPMB key will not be burned. Signed-off-by: Henry Beberman <hebeberm@microsoft.com>
