Subject: [PATCH v4 3/7] firmware: smccc: Add the definition for SMCCCv1.2 version/error codes
Date: Mon, 18 May 2020 10:12:18 +0100	[thread overview]
Message-ID: <20200518091222.27467-4-sudeep.holla@arm.com> (raw)
In-Reply-To: <20200518091222.27467-1-sudeep.holla@arm.com>

Add the definition for SMCCC v1.2 version and new error code added.
While at it, also add a note that ARM DEN 0070A is deprecated and is
now merged into the main SMCCC specification(ARM DEN 0028C).
