Subject: [PATCH v2 0/2] No access to CAAM page 0 registers
Date: Wed, 22 Mar 2023 07:17:14 +0100 [thread overview]
Message-ID: <20230322061716.3195841-1-meenakshi.aggarwal@nxp.com> (raw)
In-Reply-To: <20230302062055.1564514-3-meenakshi.aggarwal@nxp.com>
From: Meenakshi Aggarwal <meenakshi.aggarwal@nxp.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
