> Subject: [edk2-devel] [PATCH v2] BaseTools: Add support for version 3 of FMP
> Image Header structure
>
> Add support for the ImageCapsuleSupport field, introduced in version 3
> of the EFI_FIRMWARE_MANAGEMENT_CAPSULE_IMAGE_HEADER structure. This
> structure member is used to indicate if the corresponding payload has
> support for authentication and dependency.

>
> Changes since v1:
> - Reword the patch header to get rid of the PatchCheck warning
> - Make passing of ImageCapsuleSupport parameter to the AddPayload
> function as an optional parameter to maintain backward compatibility
> - Declare the values of CAPSULE_SUPPORT_DEPENDENCY and
> CAPSULE_SUPPORT_AUTHENTICATION in the FmpCapsuleHeaderClass and use
> those in the GenerateCapsule script
