This package provides an implementation of a Firmware Management Protocol instance that supports the update of firmware storage devices using UEFI Capsules. The behavior of the Firmware Management Protocol instance is customized using libraries and PCDs.
Based on content from the following branch:
https://github.com/Microsoft/MS_UEFI/tree/share/MsCapsuleSupport/MsCapsuleUpdatePkg
- FmpDeviceLib - Provides firmware device specific services to support updates of a firmware image stored in a firmware device.
- CapsuleUpdatePolicyLib - Provides platform policy services used during a capsule update.
- FmpPayloadHeaderLib - Provides services to retrieve values from a capsule's FMP Payload Header. The structure is not included in the library class. Instead, services are provided to retrieve information from the FMP Payload Header. If information is added to the FMP Payload Header, then new services may be added to this library class to retrieve the new information.
- PcdFmpDeviceTestKeySha256Digest - The SHA-256 hash of a PKCS7 test key that is used to detect if a test key is being used to authenticate capsules. Test key detection is disabled by setting the value to {0}.
- PcdFmpDeviceProgressColor - The color of the progress bar during a firmware update.
- PcdFmpDeviceImageIdName - The Null-terminated Unicode string used to fill in the ImageIdName field of the EFI_FIRMWARE_IMAGE_DESCRIPTOR structure that is returned by the GetImageInfo() service of the Firmware Management Protocol for the firmware device.
- PcdFmpDeviceBuildTimeLowestSupportedVersion - The build time value used to fill in the LowestSupportedVersion field of the EFI_FIRMWARE_IMAGE_DESCRIPTOR structure that is returned by the GetImageInfo() service of the Firmware Management Protocol.
- PcdFmpDeviceProgressWatchdogTimeInSeconds - The time in seconds to arm a watchdog timer during the update of a firmware device.
- PcdFmpDevicePkcs7CertBufferXdr - One or more PKCS7 certificates used to verify a firmware device capsule update image.
- PcdFmpDeviceLockEventGuid - An event GUID that locks the firmware device when the event is signaled.
