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"
v1: https://lore.kernel.org/all/20240325114642.3664840-1-ghidoliemanuele@gmail.com/
