Based on content from the following branch:
https://github.com/Microsoft/MS_UEFI/tree/share/MsCapsuleSupport/MsCapsuleUpdatePkg
Create FmpDevicePkg with library classes and PCDs used to
customize the behavior of a Firmware Management Protocol
instance.
Library Classes
===============
* 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.
PCDs set per module
====================
* PcdFmpDeviceSystemResetRequired - Indicates if a full
system reset is required before a firmware update to a
firmware devices takes effect
* 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.
PCDs set per module or for entire platform
==========================================
* 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.

From: Michael D Kinney @ 2018-05-29 22:37 UTC (permalink / raw)
To: edk2-devel; +Cc: Kinney, Michael D, Sean Brogan, Jiewen Yao
From: "Kinney, Michael D" <michael.d.kinney@intel.com>
https://bugzilla.tianocore.org/show_bug.cgi?id=922
Based on content from the following branch:
https://github.com/Microsoft/MS_UEFI/tree/share/MsCapsuleSupport/MsCapsuleUpdatePkg
Add library instances for FmpDeviceLib, CapsuleUpdatePolicyLib,
and FmpPayloadHeaderLib.
Library Classes
===============
* FmpDeviceLibNull - Non-functional template of the FmpDeviceLib
that can be used as a starting point for an FmpDeviceLib for
a specific firmware storage device.
* CapsuleUpdatePolicyLibNull - Functional template of the
CapsuleUpdatePolicyLib that can be used as a starting point
of a platform specific implementation.
* FmpPayloadHeaderLibV1 - Version 1 of the FmpPayloadHeaderLib.
This library is indented to be used "as is" with no need for
any device specific or platform specific changes.

To: edk2-devel; +Cc: Kinney, Michael D, Sean Brogan, Jiewen Yao
From: "Kinney, Michael D" <michael.d.kinney@intel.com>
https://bugzilla.tianocore.org/show_bug.cgi?id=922
Based on content from the following branch:
https://github.com/Microsoft/MS_UEFI/tree/share/MsCapsuleSupport/MsCapsuleUpdatePkg
The FmpDxe directory contains 2 INF files. FmpDxe.inf
is a DXE driver that is used in a platform to add a
Firmware Management Protocol for firmware device that
supports firmware updates.
FmpDxeLib.inf is a NULL library instance with the exact
same functionality as FmpDxe.inf, but allows the the
Firmware Management Protocol feature to be added to
an existing device driver.
The FmpDxe component is intended to be used "as is"
with no need for any device specific or platform specific
changes.

+ Updates the firmware image of the device.

+ This function returns EFI_UNSUPPORTED if the firmware image is not updatable.

+ before proceeding to do the firmware image update.
+ - Validate the image authentication if image has attribute
+ IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED. The function returns
+ EFI_SECURITY_VIOLATION if the validation fails.
+ - Validate the image is a supported image for this device. The function returns EFI_ABORTED if
+ the image is unsupported. The function can optionally provide more detailed information on
+ why the image is not a supported image.
+ - Validate the data from VendorCode if not null. Image validation must be performed before
+ VendorCode data validation. VendorCode data is ignored or considered invalid if image
+ validation failed. The function returns EFI_ABORTED if the data is invalid.
+
+ VendorCode enables vendor to implement vendor-specific firmware image update policy. Null if
+ the caller did not specify the policy or use the default policy. As an example, vendor can implement
+ a policy to allow an option to force a firmware image update when the abort reason is due to the new
+ firmware image version is older than the current firmware image version or bad image checksum.
+ Sensitive operations such as those wiping the entire firmware image and render the device to be
+ non-functional should be encoded in the image itself rather than passed with the VendorCode.
+ AbortReason enables vendor to have the option to provide a more detailed description of the abort
+ reason to the caller.
