From: Emanuele Ghidoli <[email protected]>
This series allows using Freescale CAAM Job Ring from Linux without having
OP-TEE,
this is needed for example on Toradex Colibri iMX7 where we just have U-Boot +
Linux kernel.
To achieve this add a new config option to allow the non-secure world to access
job rings.
The functionality has been broken since U-Boot v2019.07, with commit
51f1357f3428
("Revert "drivers/crypto/fsl: assign job-rings to non-TrustZone"")

v2:
* Kconfig: spelt "CAAM" instead of caam
* Kconfig: removed "default=n"
