f65ee99b9d mkeficapsule: Add support for setting OEM flags in capsule header
Add support for setting OEM flags in the capsule header. As per the
UEFI specification, bits 0-15 of the flags member of the capsule
header can be defined per capsule GUID.

The oemflags will be used for the FWU Multi Bank update feature, as
specified by the Dependable Boot specification[1]. Bit
15 of the flags member will be used to determine if the
acceptance/rejection of the updated images is to be done by the
firmware or an external component like the OS.

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.

d9612f4426 tools: mkeficapsule: allow for specifying GUID explicitly
The existing options, "--fit" and "--raw," are only used to put a proper
GUID in a capsule header, where GUID identifies a particular FMP (Firmware
Management Protocol) driver which then would handle the firmware binary in
a capsule. In fact, mkeficapsule does the exact same job in creating
a capsule file whatever the firmware binary type is.

To prepare for the future extension, the command syntax will be a bit
modified to allow users to specify arbitrary GUID for their own FMP driver.
OLD:
   [--fit <image> | --raw <image>] <capsule file>
NEW:
   [--fit | --raw | --guid <guid-string>] <image> <capsule file>

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.

322c813f4b mkeficapsule: Add support for embedding public key in a dtb
Add options for embedding the public key esl(efi signature list) file
to the platform's dtb. The esl file is then retrieved and used for
authenticating the capsule to be used for updating firmare components
on the platform.

The esl file can now be embedded in the dtb by invoking the following
command
mkeficapsule -K <pub_key.esl> -D <dtb>

In the scenario where the esl file is to be embedded in an overlay,
this can be done through the following command
mkeficapsule -O -K <pub_key.esl> -D <dtb>

This will create a node named 'signature' in the dtb, and the esl file
will be stored as 'capsule-key'

450596f2ac test/py: efi_capsule: test for FIT image capsule
The test can run on sandbox build and it attempts to execute a firmware
update via a capsule-on-disk, using a FIT image capsule,
CONFIG_EFI_CAPSULE_FIT.

To run this test successfully, you need configure U-Boot specifically;
See test_capsule_firmware.py for requirements, and hence it won't run
on Travis CI, at least, for now.
