Out of two possible implementation of Secure Partition Manager(SPM)
currently only Management mode (MM) design is supported and the support
for SPM based on SPCI Alpha 1 prototype has been removed.

Earlier both implementation used common build flag "ENABLE_SPM" but it
has since been decoupled and MM uses a separate build FLAG "SPM_MM".

Instructions to build it for FVP was still using "ENABLE_SPM", which has
beend corrected in this patch.

Before adding any new SPM-related components we should first do
some cleanup around the existing SPM-MM implementation. The aim
is to make sure that any SPM-MM components have names that clearly
indicate that they are MM-related. Otherwise, when adding new SPM
code, it could quickly become confusing as it would be unclear to
which component the code belongs.

The secure_partition.h header is a clear example of this, as the
name is generic so it could easily apply to any SPM-related code,
when it is in fact SPM-MM specific.

This patch renames the file and the two structures defined within
it, and then modifies any references in files that use the header.

The project has been renamed from "Arm Trusted Firmware (ATF)" to
"Trusted Firmware-A (TF-A)" long ago. A few references to the old
project name that still remained in various places have now been
removed.

This change doesn't affect any platform files. Any "ATF" references
inside platform files, still remain.

Several code blocks do not specify a language for syntax
highlighting. This results in Sphinx using a default highlighter
which is Python.

This patch adds the correct language to each code block that doesn't
already specify it.

These are no longer needed as there will always be a table of contents
rendered to the left of every page.

Some of these lists can be quite long and, when opening a page, the
reader sees nothing but a huge list of contents! After this patch,
the document contents are front-and-centre and the contents are
nicely rendered in the sidebar without duplication.

This patch attempts to standardise the document titles as well as
adding titles to documents that were missing one. The aim is to
remove needless references to "TF-A" or "Trusted Firmware" in the
title of every document and to make sure that the title matches
with the document content.

This change creates the following directories under docs/
in order to provide a grouping for the content:

- components
- design
- getting_started
- perf
- process

In each of these directories an index.rst file is created
and this serves as an index / landing page for each of the
groups when the pages are compiled. Proper layout of the
top-level table of contents relies on this directory/index
structure.

Without this patch it is possible to build the documents
correctly with Sphinx but the output looks messy because
there is no overall hierarchy.

Corrects typos in core code, documentation files, drivers, Arm
platforms and services.

None of the corrections affect code; changes are limited to comments
and other documentation.

Add a dependency for building EL3 exception handling framework(EHF)
module with the secure partition manager(SPM).

The EHF module is needed for raising the core's running priority
before the core enters the secure partition, and lowering it
subsequently on exit from the secure partition.

BL31 is running out of space, and the use-case of SPM doesn't require it
to be in SRAM. To prevent BL31 from running out of space in the future,
move BL31 to DRAM if SPM is enabled.

Secure Partition Manager design document updated to reflect the changes.

Increased the size of the stack of BL31 for builds with SPM.

The translation tables used by SPM in Arm platforms have been moved back
to the 'xlat_tables' region instead of 'arm_el3_tzc_dram'. Everything is
in DRAM now, so it doesn't make sense to treat them in a different way.

Update Arm Trusted Firmware references in the upstream documents to
Trusted Firmware-A (TF-A). This is for consistency with and
disambiguation from Trusted Firmware-M (TF-M).

Also update other Arm trademarks, e.g. ARM->Arm, ARMv8->Armv8-A.

This patch adds documentation that describes the design of the Secure
Partition Manager and the specific choices in their current
implementation.

The document "SPM User Guide" has been integrated into the design
document.
