Subject: [PATCH v2 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 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
