[edk2] [PATCH edk2-platforms 2/4] Platform/AMD/OverdriveBoard: cover secure firmware in capsule update
Posted by Ard Biesheuvel 6 years, 9 months ago
Add the first part of the flash device (FD) to the capsule image so we
can update the secure and SCP firmware in one go along with the UEFI
firmware volume (FV).
