Subject: [PATCH v5 6/6] FmpDevicePkg/FmpDeviceLib: Add Last Attempt Status to Check/Set API
Date: Thu, 15 Oct 2020 14:11:21 -0700 [thread overview]
Message-ID: <MWHPR07MB3440A743951F4DC7112E1ED6E9020@MWHPR07MB3440.namprd07.prod.outlook.com> (raw)
In-Reply-To: <20201015211121.1927-1-michael.kubacki@outlook.com>
From: Michael Kubacki <michael.kubacki@microsoft.com>
Provides the ability for a given FMP device library instance to
return a Last Attempt Status code during check image and set image
operations with FmpDeviceCheckImageEx() and FmpDeviceSetImageEx().
