From: Meenakshi Aggarwal <meenakshi.aggarwal@xxxxxxx>

This series includes patches to reduce access to page 0 registers of
CAAM from non-secure world.

In non-secure world, access to page 0 registers of CAAM is
forbidden, so we are using alias registers available in Job Ring's
register address space.

Allow CAAM's page 0 access to OPTEE, as OPTEE runs in secure world.

changes in v3:
- Fixed compile time warnings reported by kernel test robot
- incorporated review comments

changes in v2:
- Fixed compile time warnings coming with compilation flag W=1

Horia GeantA (2):
crypto: caam - reduce page 0 regs access to minimum
crypto: caam - OP-TEE firmware support
