[edk2-devel] [PATCH v3 5/6] FmpDevicePkg: Add Last Attempt Status support to dependency libs
Michael Kubacki
michael.kubacki at outlook.com
Tue Aug 18 21:16:28 UTC 2020
From: Michael Kubacki <michael.kubacki at microsoft.com>
The FMP dependency libraries are leveraged during firmware update
to check for dependencies required to update the image.
This change adds granular Last Attempt Status code support to these
services so failures can be more easily observed during the firmware
update process via Last Attempt Status codes.
