A separate design document for Measured Boot covers the porting
guidelines for the Measured Boot interfaces. As a result,
the Measured Boot interfaces have been removed from the porting
guide and a link to the Measured Boot design document has been
provided.

The FEAT_MTPMU feature disable runs very early after reset. This means,
it needs to be written in assembly, since the C runtime has not been
initialised yet.
However, there is no need for it to be initialised so soon. The PMU
state is only relevant after TF-A has relinquished control. The code
to do this is also very verbose and difficult to read. Delaying the
initialisation allows for it to happen with the rest of the PMU. Align
with FEAT_STATE in the process.
BREAKING CHANGE: This patch explicitly breaks the EL2 entry path. It is
currently unsupported.

In some build configurations TF-A can exceed the existing 256KB SRAM,
triggering a build failure. More recent versions of the base FVP allow
you to configure a larger Trusted SRAM of 512KB.
This change introduces the `FVP_TRUSTED_SRAM_SIZE` build option, which
allows you to explicitly specify how much of the Trusted SRAM to
utilise, e.g.:
FVP_TRUSTED_SRAM_SIZE=384
This allows previously-failing configurations to build successfully by
utilising more than the originally-allocated 256KB of the Trusted SRAM
while maintaining compatibility with older configurations/models that
only require/have 256KB.

For a pretty implementation and straightforward code, the CVE/erratum
dispatching of the errata status reporting was done with a macro,
closely following the old code. Unfortunately, this produces a function
that was over a kilobyte in size, which unsurprisingly doesn't fit on
some platforms.
Convert the macro to a proper C function and call it once. Also hide the
errata ordering checking behind the FEATURE_DETECTION flag to further
save space. This functionality is not necessary for most builds.
Development and platform bringup builds, which should find this
functionality useful, are expected to have FEATURE_DETECTION enabled.
This reduces the function to under 600 bytes.

Add symbols to mark end of TEXT/RODATA before page alignment.
Similar change was done by commit 8d69a03f6a ("Various
improvements/cleanups on the linker scripts") for
RO_END/COHERENT_RAM. These symbols help to know how much free
space is in the final binary because of page alignment.
Also show all *UNALIGNED__ symbols via poetry.
For example:
poetry run memory -p zynqmp -b debug

Fixes errors encountered when handling SVG graphics, unicode characters,
and deeply nested lists (i.e. in the change log) with the `latexpdf`
docs build. Adds `sphinxcontrib-svg2pdfconverter` to allow embedding SVG
images into PDF files; changes the LaTeX engine to XeLaTex to provide
wider support for unicode characters (see [1] for more details); and
increases the maximum list depth.

Add a new page in TF-A documentation for clarifying the process to
elect a new maintainer. This builds on top of the Trusted Firmware
process [1], with the following TF-A specific details:
- Must have contributed to the project for at least a couple of years.
- Must dedicate at least 2 hours a week for maintainer duties.
- Details about the election process. In particular, setting a
one-calendar-week deadline for other maintainers to raise
objections.

This patch adds a new optional member `pwr_domain_validate_suspend` to
the `plat_psci_ops_t` structure that allows a platform to optionally
perform platform specific validations in OS-initiated mode. This is
conditionally compiled into the build depending on the value of the
`PSCI_OS_INIT_MODE` build option.
In https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/17682,
the return type of the `pwr_domain_suspend` handler was updated from
`void` to `int` to allow a platform to optionally perform platform
specific validations in OS-initiated mode. However, when an error code
other than `PSCI_E_SUCCESS` is returned, the current exit path does not
undo the operations in `psci_suspend_to_pwrdown_start`, and as a result,
the system ends up in an unexpected state.
The fix in this patch prevents the need to undo the operations in
`psci_suspend_to_pwrdown_start`, by allowing the platform to first
perform any necessary platform specific validations before the PSCI
generic code proceeds to the point of no return where the CPU_SUSPEND
request is expected to complete successfully.
