Transfering the regions of ddr memory to additionally protect is very much
specific to some rockchip internal first stage bootloader and doesn't get
used in either mainline uboot or even Rockchip's published vendor uboot
sources.
This results in a big error
ERROR: over or zero region, nr=0, max=10
getting emitted on every boot for most users and such a message coming
from early firmware might actually confuse developers working with the
system.
As this mechanism seems to be only be used by Rockchip's internal miniloader
hide it behind a build conditional, so it doesn't confuse people too much.

So far the px30-related ddr security was loading data for regions to secure
from a pre-specified memory location and also setting region0 to secure
the first megabyte of memory in hard-coded setting (top=0, end=0, meaning
1MB).
To make things more explicit and easier to read add a function doing
the settings for specified memory areas, like other socs have and also
add an assert to make sure any descriptor read from memory does not
overlap the TZRAM security in region0 and TEE security in region1.

The calls to secure ddr regions on rk3288 and rk3399 use parameters of
base and size - as it custom for specifying memory regions, but the
functions themself expect start and endpoints of the area.
This only works by chance for the TZRAM, as it starts a 0x0 and therefore
its end location is the same as its size.
To not fall into a trap later on adapt the functions to really take
base+size parameters.

The agreed upon division of early boot locations is 0x40000 for bl31
to leave enough room for u-boot-spl and 0x100000 for bl33 (u-boot).
rk3288 and rk3399 already correctly secure the ddr up to the 1MB boundary
so pull the other platforms along to also give the Rockchip TF-A enough
room to comfortably live in.

The list of upstream platforms on the index page is growing
quite long, especially with all the FVP variants being listed
individually.
This patch leverages the "Platform Ports" chapter in the docs
table of contents to condense this information. Almost all
platform ports now have documentation, so the table of
contents serves as the list of upstream platforms by itself.
For those upstream platforms that do not have corresponding
documentation, the top-level "Platform Ports" page mentions
them individually. It also mentions each Arm FVP, just as
the index page did before.
Note that there is an in-progress patch that creates new
platform port documentation for the Arm Juno and Arm FVP
platforms, so this list of "other platforms" will soon be
reduced further as those platforms become part of the
table of contents as well.

The index.rst page is now the primary landing page for the TF-A
documentation. It contains quite a lot of content these days,
including:
- The project purpose and general intro
- A list of functionality
- A list of planned functionality
- A list of supported platforms
- "Getting started" links to other documents
- Contact information for raising issues
This patch creates an "About" chapter in the table
of contents and moves some content there. In order,
the above listed content:
- Stayed where it is. This is the right place for it.
- Moved to About->Features
- Moved to About->Features (in subsection)
- Stayed where it is. Moved in a later patch.
- Was expanded in-place
- Moved to About->Contact

The WARMBOOT_ENABLE_DCACHE_EARLY allows caches to be turned on early during
the boot. But the xlat_change_mem_attributes_ctx() API did not do the required
cache maintenance after the mmap tables are modified if
WARMBOOT_ENABLE_DCACHE_EARLY is enabled. This meant that when the caches are turned
off during power down, the tables in memory are accessed as part of cache
maintenance for power down, and the tables are not correct at this point which
results in a data abort.
This patch removes the optimization within xlat_change_mem_attributes_ctx()
when WARMBOOT_ENABLE_DCACHE_EARLY is enabled.

We would need to update this version for the release but, in fact,
it is not required for our publishing workflow; the hosted version
of the docs uses git commit/tag information in place of these
variables anyway.
Instead of updating the version, just remove these variables
entirely.

The version of the Linaro release that is used for testing was
updated in 35010bb8 and the user guide was updated with the
correct version, however the version is also mentioned on the
index page and that was missed. Update the index page with the
new version.
We can come back and de-duplicate this content later, to ease
future maintenance.

The readme.rst file in the project root is the front-page that
is displayed on Github and if viewing the TF-A repository on
git.trustedfirmware.org in the "about" view. It now contains a
small amount of stub content, and directs readers to the
ReadTheDocs documentation via trustedfirmware.org/docs/tf-a.
The Github renderer is displaying the content fine but the cgit
viewer displays some "backlink" errors because some content
substitutions were left in place (terms surrounded by pipe
symbols), e.g. |TF-A|.
This patch removes those substitutions, that are not supported
by cgit, and also updates one heading to clarify where to find
the new docs.

The readme.rst and license.rst files in the project root overlap
with the index.rst and license.rst files in the docs/ folder. We
need to use the latter when building the documentation, as Sphinx
requires all included files to be under a common root. However,
the files in the root are currently used by the cgit and Github
viewers.
Using symlinks in Git presents some difficulties so the best
course of action is likely to leave these files but in stub form.
The license.rst file in the root will simply tell the reader to
refer to docs/license.rst.
The readme.rst file will contain a small amount of content that
is derived from the docs/index.rst file, so that the Github main
page will have something valid to show, but it will also contain
a link to the full documentation on ReadTheDocs.

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.

Coherent I-cache is causing a prefetch violation where when the core
executes an instruction that has recently been modified, the core might
fetch a stale instruction which violates the ordering of instruction
fetches.
The workaround includes an instruction sequence to implementation
defined registers to trap all EL0 IC IVAU instructions to EL3 and a trap
handler to execute a TLB inner-shareable invalidation to an arbitrary
address followed by a DSB.
