[PATCH v2 0/3] crypto/fsl: allow accessing Job Ring from non-TrustZone

[Emanuele Ghidoli]

From: Emanuele Ghidoli <emanuele.ghidoli at toradex.com>

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"")
