Subject: [PATCH 0/2] No access to CAAM page 0 registers

From: Meenakshi Aggarwal <meenakshi.aggarwal@....com>

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.

  crypto: caam - reduce page 0 regs access to minimum
