6da9271af1 mkeficapsule: Add support for generating empty capsules
The Dependable Boot specification[1] describes the structure of the
firmware accept and revert capsules. These are empty capsules which
are used for signalling the acceptance or rejection of the updated
firmware by the OS. Add support for generating these empty capsules.

2eda55e4c9 mkeficapsule: Remove raw and FIT GUID types
While building a capsule, the GUID value of that specific image is to
be passed through the --guid command option to the mkeficapsule
tool instead of using one of --raw or --fit options, where the GUID
value passed through the command line option is the image GUID.

This renders the EFI_FIRMWARE_IMAGE_TYPE_UBOOT_FIT_GUID and
EFI_FIRMWARE_IMAGE_TYPE_UBOOT_RAW_GUID values superfluous. Remove the
--raw and --fit command line options as well. Also modify the
mkeficapsule man page to reflect this change.

16abff246b tools: mkeficapsule: add firmware image signing
With this enhancement, mkeficapsule will be able to sign a capsule
file when it is created. A signature added will be used later
in the verification at FMP's SetImage() call.

To do that, we need specify additional command parameters:
  -monotonic-cout <count> : monotonic count
  -private-key <private key file> : private key file
  -certificate <certificate file> : certificate file
Only when all of those parameters are given, a signature will be added
to a capsule file.

Users are expected to maintain and increment the monotonic count at
every time of the update for each firmware image.
