Subject: [PATCH v4 04/14] ArmPkg: Introduce support for PcdFfaEnable
Date: Wed, 17 Feb 2021 16:57:07 +0530 [thread overview]
Message-ID: <20210217112717.6820-5-sughosh.ganu@linaro.org> (raw)
In-Reply-To: <20210217112717.6820-1-sughosh.ganu@linaro.org>
The Secure Partition(SP) can request services from the Secure
Partition Manager Core(SPMC) either through FF-A calls or through the
existing SVC calls. Add a feature flag Pcd for enabling the FF-A
method -- when this is set to FALSE, the SP uses the existing SVC
calls for making the requests.
Signed-off-by: Sughosh Ganu <sughosh.ganu@linaro.org>

Changes since V3:
* Put the PcdFfaEnable under the PcdsFeatureFlag.AARCH64 section to
avoid build breakage for the X64 StandaloneMm builds.
