doc: Move platform list to the Platform Ports index page
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.

xlat_table_v2: Fix enable WARMBOOT_ENABLE_DCACHE_EARLY config
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.

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.

doc: Convert internal links to RST format
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.

Make the spinlock implementation use ARMv8.1-LSE CAS instruction based

The previous CAS spinlock implementation had a bug wherein the spin_unlock()
implementation had an `sev` after `stlr` which is not sufficient. A dsb is
needed to ensure that the stlr completes prior to the sev. Having a dsb is
heavyweight and a better solution would be to use load exclusive semantics
to monitor the lock and wake up from wfe when a store happens to the lock.

qemu/qemu_sbsa: Adding memory mapping for both FLASH0/FLASH1
This patch adds mapping for secure FLASH0 for qemu/virt and
qemu/qemu_sbsa platforms. This change is targeted for sbsa but since both
platforms share common code, changes in common defines was necessary.
For qemu_sbsa, this patch adds necessary mapping in order to boot without
semi-hosting from secure FLASH0. EFI need to stay in FLASH1 (share it with
variables) since it need to "run in place" in non secure domain. Changes
for this are under RFC at edk2-platforms mailing list:
https://patches.linaro.org/patch/171327/
(edk2-platforms/Platform/Qemu/SbsaQemu/SbsaQemu.dsc).

should be orthogonal to existing assumptions while giving possibility to
store both bl1 and fip in FLASH0 at some point (additional changes required
for that).

rpi4: Accommodate "armstub8.bin" header at the beginning of BL31 image
The Raspberry Pi GPU firmware checks for a magic value at offset 240
(0xf0) of the armstub8.bin image it loads. If that value matches,
it writes the kernel load address and the DTB address into subsequent
memory locations.
We can use these addresses to avoid hardcoding these values into the BL31
image, to make it more flexible and a drop-in replacement for the
official armstub8.bin.
Reserving just 16 bytes at offset 240 of the final image file is not easily
possible, though, as this location is in the middle of the generic BL31
entry point code.
However we can prepend an extra section before the actual BL31 image, to
contain the magic and addresses. This needs to be 4KB, because the
actual BL31 entry point needs to be page aligned.
Use the platform linker script hook that the generic code provides, to
add an almost empty 4KB code block before the entry point code. The very
first word contains a branch instruction to jump over this page, into
the actual entry code.
This also gives us plenty of room for the SMP pens later.

Add basic support for Raspberry Pi 4
The Raspberry Pi 4 is a single board computer with four Cortex-A72
cores. From a TF-A perspective it is quite similar to the Raspberry Pi
3, although it comes with more memory (up to 4GB) and has a GIC.
This initial port though differs quite a lot from the existing rpi3
platform port, mainly due to taking a much simpler and more robust
approach to loading the non-secure payload:
The GPU firmware of the SoC, which is responsible for initial platform
setup (including DRAM initialisation), already loads the kernel, device
tree and the "armstub" into DRAM. We take advantage of this, by placing
just a BL31 component into the armstub8.bin component, which will be
executed first, in AArch64 EL3.
The non-secure payload can be a kernel or a boot loader (U-Boot or
EDK-2), disguised as the "kernel" image and loaded by the GPU firmware.
So this is just a BL31-only port, which directly drops into EL2
and executes whatever has been loaded as the "kernel" image, handing
over the DTB address in x0.
