Subject: [PATCH v5 04/14] ArmPkg: Introduce support for PcdFfaEnable
Date: Fri, 19 Feb 2021 12:05:57 +0530	[thread overview]
Message-ID: <20210219063607.27920-5-sughosh.ganu@linaro.org> (raw)
In-Reply-To: <20210219063607.27920-1-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.
