From a54cdba5b641391c0f1fd464c42c1b4c196206b7 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Sun, 15 Oct 2017 10:37:37 +0100 Subject: Platforms/AMD/Overdrive: add signed capsule update support Wire up the various modules and boilerplate configuration snippets to implement signed capsule update for AMD Overdrive. Note that this uses the insecure default key. The secure firmware on this SoC does not implement warm reboot, so we cannot support capsules that persist across reset. Instead, the capsule may be installed using CapsuleApp (from MdeModulePkg), from the UEFI Shell prompt.
