[v7,00/11] Integrate EFI capsule tasks into u-boot's build flow

This patchset aims to bring two capsule related tasks under the u-boot
build flow.

One is the embedding of the public key into the platform's dtb. The
public key is in the form of an EFI Signature List(ESL) file and is
used for capsule authentication. This is being achieved by adding the
signature node containing the capsule public key in the architecture's
u-boot.dtsi file. Currently, the u-boot.dtsi file has been added for
the sandbox and arm architectures. The path to the ESL file is being
provided through a Kconfig symbol(CONFIG_EFI_CAPSULE_ESL_FILE).

Changes have also been made to the test flow so that the keys used for
signing the capsule, and the ESL file, are generated prior to invoking
the u-boot's build, which enables embedding the ESL file into the dtb
as part of the u-boot build.

The other task is related to generation of capsules. The capsules can
be generated as part of u-boot build, and this is being achieved
through binman, by adding a capsule entry type. The capsules can be
generated by specifying the capsule parameters as properties under the
capsule entry node.

Changes have also been made to the efi capsule update feature testing
setup on the sandbox variants. Currently, the capsule files and the
public key ESL file are generated after u-boot has been built. This
logic has been changed so that the capsule input files along with the
keys needed for capsule signing and authentication are generated prior
to initiation of the u-boot build. The placement of all the keys and
public key certificates needed for signing and authenticating capsules
is under the board/sandbox/ directory. The other input files needed
for testing the EFI capsule update feature are being generated through
binman for the sandbox platform.

The document has been updated to reflect the above changes.

Changes since V6:

After discussing with Simon and Tom over irc, this series puts only
the keys and cert files under the board/sandbox/ directory. The other
set of capsule input files needed for capsule update feature testing
are being generated through binman.

The other patch specific changes are as under.

* New patch that puts the keys and cert files under board/sandbox/
  directory as suggested Simon Glass.
* Populate the CONFIG_EFI_CAPSULE_ESL_FILE symbol for sandbox and
  sandbox_flattree which enable capsule authentication.
* New patch which has been split up from the binman capsule entry
  support patch from earlier version, as suggested by Simon Glass.
* Enables mkeficapsule tool for all sandbox variants, instead of only
  for sandbox_spl variant.
* Split the changes for mkeficapsule btool into a separate patch, as
  suggested by Simon Glass.
* Use the word commandline consistently, as suggested by Simon Glass.
* Add macros for the GUID strings in sandbox_efi_capsule.h
* Highlight that the private and public keys are mandatory for capsule
  signing.
* Add a URL link to the UEFI spec, as used in the rst files.
* Use local vars for private and public keys in BuildSectionData()
* Use local vars for input payload and capsule filenames in
  BuildSectionData().
* Drop the ProcessContents() and SetImagePos() as the superclass
  functions suffice.
* Use GUID macro names in the capsule test dts files.
* Rename efi_capsule_payload.bin to capsule_input.bin.
* Use macros defined in sandbox_efi_capsule for GUIDs and capsule
  input filenames.
* Generate the capsule input files through binman text entries.
* New patch for fixing CI trace test failure.
