imx: imx_caam: Add code to initialize the CAAM job-rings to NS-world
This patch defines the most basic part of the CAAM and the only piece of the CAAM silicon we are really interested in, in ATF, the CAAM control structure. The CAAM itself is a huge address space of some 32k, way out of scope for the purpose we have in ATF. This patch adds a simple CAAM init function that assigns ownership of the CAAM job-rings to the non-secure MID with the ownership bit set to non-secure. This will allow later logic in the boot process such as OPTEE, u-boot and Linux to assign job-rings as appropriate, restricting if necessary but leaving open the main functionality of the CAAM to the Linux NS runtime.
