Commit22191ac353("drivers/crypto/fsl: assign job-rings to non-TrustZone") breaks HABv4 encrypted boot support in the following i.MX devices: - i.MX6UL - i.MX7S - i.MX7D - i.MX7ULP For preparing a HABv4 encrypted boot image it's necessary to encapsulate the generated DEK in a blob. In devices listed above the blob generation function takes into consideration the Job Ring TrustZone ownership configuration (JROWN_NS) and can be only decapsulated by the same configuration. The ROM code expects DEK blobs encapsulated by the Secure World environments which commonly have JROWN_NS = 0. As U-Boot is running in Secure World we must have JROWN_NS = 0 so the blobs generated by dek_blob tool can be decapsulated by the ROM code. Job-rings assignment is now handled in OP-TEE OS, this commit can be safely reverted. https://github.com/OP-TEE/optee_os/pull/2986 This reverts commit22191ac353.
