Subject: [PATCH v8 01/21] ArmPkg: Add ARM SMC Architecture functions to ArmStdSmc.h
Date: Sun,  7 Feb 2021 17:52:34 -0700	[thread overview]
Message-ID: <20210208005254.12176-2-rebecca@nuviainc.com> (raw)
In-Reply-To: <20210208005254.12176-1-rebecca@nuviainc.com>

The ARM SMC Architecture functions were missing from ArmStdSmc.h.
Add them, based on the SMC Calling Convention version 1.2 specification.
