Subject: [RFC PATCH v4 05/12] MdePkg/Library: Add StandaloneMmRuntimeDxe library
Date: Tue, 11 Dec 2018 11:51:35 +0530 [thread overview]
Message-ID: <1544509302-1000-6-git-send-email-jagadeesh.ujja@arm.com> (raw)
In-Reply-To: <1544509302-1000-1-git-send-email-jagadeesh.ujja@arm.com>
To resuse some the libraries in both MM and non-MM mode, a mechanism to
determine the execution mode is required, i.e, in MM or non-MM. Add a
new library for use by non-MM code to determine the current execution
mode.
