According to Platform Initialization (PI) Specification [1] and
discussion on edk2 mailing list [2],
StandaloneMm shouldn't create Hob but it should be passed from TF-A.
IOW, TF-A should pass boot information via HOB list to initialise
StandaloneMm properly.
And this HOB lists could be delivered via
- SPM_MM: Transfer List according to the firmware handoff spec[3]
- FF-A v1.1 >= : FF-A boot protocol.
This patch introduces a TF-A HOB creation library and
some of definitions which StandaloneMm requires to boot.

According to Platform Initialization (PI) Specification [1] and
Discussion on edk2 mailing list [2],
StandaloneMm shouldn't create Hob but it should be passed from TF-A.
IOW, TF-A should pass boot information via PHIT Hob to initialize
StandaloneMm properly.
This patch modifies Hob creation code from edk2 codebase
so that TF-A could create Hob information properly to boot StandaloneMm

The DPE implementation in RSS is aligned with the
Open Profile for DICE specification:
https://pigweed.googlesource.com/open-dice/
Type definitions are needed to specify the input
values for the DPE service. Instead of mandating to
clone the entire open-dice repo, the following file
is copied from the repository:
https://pigweed.googlesource.com/open-dice/+/refs/heads/main/include/dice/dice.h
Git SHA of the source version: cf549422e3
This is external code, with Apache 2.0 license, therefore
the license.rst is updated accordingly and a copy of this
license is also added.

The arm-gic.h was a concatenation of arm-gic.h and irq.h from Linux.
Just copy the 2 files here. They both have MIT license which is accepted
in TF-A.
With this alignment, a new macro is added (GIC_CPU_MASK_SIMPLE).

The `arm-gic.h` file distributed by the Linux kernel is disjunctively
dual-licensed under the GPL-2.0 or MIT licenses, but the BSD-3-Clause
license has been applied in violation of the requirements of both
licenses. This change ensures the file is correctly licensed under the
terms of the MIT license, and that we comply with it by distributing a
copy of the license text.

Currently links between documents are using the format:
<path/to/><filename>.rst
This was required for services like GitHub because they render each
document in isolation - linking to another document is like linking
to any other file, just provide the full path.
However, with the new approach, the .rst files are only the raw
source for the documents. Once the documents have been rendered
the output is now in another format (HTML in our case) and so,
when linking to another document, the link must point to the
rendered version and not the .rst file.
The RST spec provides a few methods for linking between content.
The parent of this patch enabled the automatic creation of anchors
for document titles - we will use these anchors as the targets for
our links. Additional anchors can be added by hand if needed, on
section and sub-section titles, for example.
An example of this new format, for a document with the title
"Firmware Design" is :ref:`Firmware Design`.
One big advantage of this is that anchors are not dependent on
paths. We can then move documents around, even between directories,
without breaking any links between documents. Links will need to be
updated only if the title of a document changes.

Previously the readme.rst file served as the entrypoint for the
documentation. With a Sphinx build the top-level document is set
to be index.rst as it contains the primary document index.
This patch moves some content from readme.rst into index.rst and
splits the license information out into license.rst.
