Subject: [PATCH v3 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.

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
