Subject: Re: [PATCH v9 00/13] Add the VariablePolicy feature
Date: Thu, 19 Nov 2020 08:15:13 -0800 [thread overview]
Message-ID: <345CC9C5-CCDB-4F76-A636-238B116DE217@gmail.com> (raw)
In-Reply-To: <0c1ea26d-e7f2-11d7-b7d1-66cd5def51b3@arm.com>
Those bugs and recommendations were sent out months ago. Several platforms have staged the changes already.
You need to add the library class to your DSC.
