This patch documents the support for the newly introduced
CTX_INCLUDE_SVE_REGS build flag. Since this build flag is influenced
by other build flags, the relevant sections have been updated with
proper guidance.
This patch also documents the SEPARATE_SIMD_SECTION build flag.

Introduce a new feature state CHECK_ASYMMETRIC to cater for the features
which are asymmetric across cores. This state is useful for platforms
which has architectural asymmetric cores (A feature is only present in
one type of core e.g. big).
This state is similar to FEAT_STATE_CHECK (dynamic detection) except
that feature state is also checked on each core during warmboot path and
override the context (just for asymmetric features) which was setup by
core executing CPU_ON call.
Only Non-secure context will be re-checked as secure and realm context
is created on same core.

The problem that this resolves is a bit involved; the following
must be met at the same time for some function <to_be_wrapped>:
* to_be_wrapped must be specified as part of the romlib
* to_be_wrapped must _not_ be referenced by any translation unit
in TF-A
* to_be_wrapped must be referenced by a translation unit in a
dependent library, mbedtls for example.
Under these circumstances, to_be_wrapped will not be wrapped, and
will instead reference its original definition while simultaneously
residing in romlib.
This is a side effect of two issues with romlib prior to this patch:
1 to_be_wrapped is expected to wrap by duplicating its definition.
This causes any condition that links against both the base and
wrapper functions to be a link error (duplicate symbol definition).
2 to_be_wrapped is in its own translation unit
This causes the wrappers to be used by TF-A in an as needed.
The duplicate function definitions can be worked around using the
linker's `--wrap` flag, which redirects all references to a symbol
to resolve to `__wrap_<symbol>` and the original symbol to be
available as `__real_<symbol>`. Most of the changes handle creating
this arguments and passing them to the linker.
Further, once you use the linker's wrap, you will encounter another
issue: if TF-A does not use a function, its wrapper is not present.
This causes link issues when a library and not TF-A uses the wrapper.
Note that this issue would have been resolved previously by ignoring
the wrapper and using the base definition.
This further issue is worked around by concatenating the assembly for
all of the wrappers into a single translation unit. It's possible to
work around this issue in a few other ways, including reordering the
libraries passed to the linker to place libwrapper.a last or grouping
the libraries so that symbols from later libraries may be resolved
with prior libraries.
I chose the translation unit concatenation approach as it revealed
that a jumptable has duplicate symbols within it.

Hence, this binding document is updated to reflect new additions made

Also, few fields were incorrectly identified as mandatory. Necessary

This commit adds a command create-from-yaml to tlc, which
creates a transfer list from a yaml file. It also changes
the files structure of the fixtures in the unit tests so
they are in a directory called trusted-firmware-a. This
is necessary because blob file paths in the yaml file are
relative to the root of TF-A.
The blob files are not verified by TLC, so it can be used
to load arbitrary binary information into the transfer
list. The authenticity of the transfer list must be
ensured by the loader.

Transfer List Compiler is a command line tool that enables the static
generation of TL's compliant with version 0.9 of the firmware handoff
specification. The intent of this tool is to support information passing
via the firmware handoff framework to bootloaders that run without
preceding images (i.e. `RESET_TO_BL31`).
It currently allows for TL's to be statically generated from blobs of
data, and modified by removing/adding TE's. Future work will provide
support for TL generation from configuration file.

Update Versal platform to enable runtime detection of variants instead
of relying on the build argument VERSAL_PLATFORM.
Integrate functionality for identifying the board variant during
runtime, allowing dynamic adjustment of CPU and UART clock values
accordingly.
Print the runtime board information during boot.
This advancement streamlines the build process by eliminating
dependencies on variant-specific builds, enabling the use of a single
binary for multiple variants.
Removing all the platform related constants for versal_virt,SPP,EMU as
they are not used.

This change introduces a few helper variables for dealing with verbose
and silent build modes: `silent`, `verbose`, `q` and `s`.
The `silent` and `verbose` variables are boolean values determining
whether the build system has been configured to run silently or
verbosely respectively (i.e. with `--silent` or `V=1`).
These two modes cannot be used together - if `silent` is truthy then
`verbose` is always falsy. As such:
make --silent V=1
... results in a silent build.
In addition to these boolean variables, we also introduce two new
variables - `s` and `q` - for use in rule recipes to conditionally
suppress the output of commands.
When building silently, `s` expands to a value which disables the
command that follows, and `q` expands to a value which supppresses
echoing of the command:
$(s)echo 'This command is neither echoed nor executed'
$(q)echo 'This command is executed but not echoed'
When building verbosely, `s` expands to a value which disables the
command that follows, and `q` expands to nothing:
$(s)echo 'This command is neither echoed nor executed'
$(q)echo 'This command is executed and echoed'
In all other cases, both `s` and `q` expand to a value which suppresses
echoing of the command that follows:
$(s)echo 'This command is executed but not echoed'
$(q)echo 'This command is executed but not echoed'
The `s` variable is predominantly useful for `echo` commands, where you
always want to suppress echoing of the command itself, whilst `q` is
more useful for all other commands.
