Add the essentials for supporting a Sphinx documentation build:
- A makefile under docs/ to invoke Sphinx with the desired output
format
- A Sphinx master configuration file (conf.py)
- A single, top-level index page (index.rst)
- The TF.org logo that is integrated in the the sidebar of the
rendered output

1) One space was missing from the indentation and, hence, rendering error
was generated in the user guide.
2) Partially reword Pointer Authentication related info.

The workarounds for errata 1257314, 1262606, 1262888 and 1275112 are
added to the Cortex-A76 cpu specific file. The workarounds are disabled
by default and have to be explicitly enabled by the platform integrator.

This patch fixes this issue:
https://github.com/ARM-software/tf-issues/issues/660
The introduced changes are the following:
1) Some cores implement cache coherency maintenance operation on the
hardware level. For those cores, such as - but not only - the DynamIQ
cores, it is mandatory that TF-A is compiled with the
HW_ASSISTED_COHERENCY flag. If not, the core behaviour at runtime is
unpredictable. To prevent this, compile time checks have been added and
compilation errors are generated, if needed.
2) To enable this change for FVP, a logical separation has been done for
the core libraries. A system cannot contain cores of both groups, i.e.
cores that manage coherency on hardware and cores that don't do it. As
such, depending on the HW_ASSISTED_COHERENCY flag, FVP includes the
libraries only of the relevant cores.
3) The neoverse_e1.S file has been added to the FVP sources.

On certain platforms it does not make sense to generate
TF-A binary images. For example a platform could make use of serveral
memory areas, which are non-continuous and the resulting binary
therefore would suffer from the padding-bytes.
Typically these platforms use the ELF image.
This patch introduces a variable DISABLE_BIN_GENERATION, which
can be set to '1' in the platform makefile to prevent the binary
generation.

The current stack-protector support is for none, "strong" or "all".
The default use of the flag enables the stack-protection to all
functions that declare a character array of eight bytes or more in
length on their stack.
This option can be tuned with the --param=ssp-buffer-size=N option.

Since STM32MP1 platform supports different boards, it is necessary
to build for a particular board. With the current instructions, the
user has to modify the DTB_FILE_NAME variable in platform.mk for
building for a particular board, but this can be avoided by passing
the appropriate board DTB name via DTB_FILE_NAME make variable.
Hence document the same in platform doc.

Support booting OP-TEE as BL32 boot stage and secure runtime
service.
OP-TEE executes in internal RAM and uses a secure DDR area to store
the pager pagestore. Memory mapping and TZC are configured accordingly
prior OP-TEE boot. OP-TEE image is expected in OP-TEE v2 format where
a header file describes the effective boot images. This change
post processes header file content to get OP-TEE load addresses
and set OP-TEE boot arguments.

Under certain near idle conditions, DSU may miss response transfers on
the ACE master or Peripheral port, leading to deadlock. This workaround
disables high-level clock gating of the DSU to prevent this.

On Cortex A9 an errata can cause the processor to violate the rules for
speculative fetches when the MMU is off but branch prediction has not
been disabled. The workaround for this is to execute an Invalidate
Entire Branch Prediction Array (BPIALL) followed by a DSB.

The implementation of the heap function plat_get_mbedtls_heap() becomes
mandatory for platforms supporting TRUSTED_BOARD_BOOT.
The shared Mbed TLS heap default weak function implementation is
converted to a helper function get_mbedtls_heap_helper() which can be
used by the platforms for their own function implementation.

This is the temporary contents page that links
to all other documents (except platform ports).
This page is needed during the
trustedfirmware.org migration, before we have a
Sphinx rendering pipeline set up, because cgit
doesn't offer a good way to view rendered docs
while browsing the tree. We need to have a links
page that can be opened from the cgit 'about'
view.

Fixed the below bugs:
1) Bug related to build flag V=1: if the flag was V=0, building with
ROMLIB would fail.
2) Due to a syntax bug in genwrappers.sh, index file entries marked as
"patch" or "reserved" were ignored.
3) Added a prepending hash to constants that genwrappers is generating.
4) Due to broken dependencies, currently the inclusion functionality is
intentionally not utilised. This is why the contents of romlib/jmptbl.i
have been copied to platform specific jmptbl.i files. As a result of the
broken dependencies, when changing the index files, e.g. patching
functions, a clean build is always required. This is a known issue that
will be fixed in the future.
