Cortex X2 erratum 2058056 is a Cat B erratum present in the X2 core.
It applies to revisions r0p0, r1p0, and r2p0 and is still open.
There are 2 ways this workaround can be accomplished, the first of
which involves executing a few additional instructions around MSR
writes to CPUECTLR when disabling the prefetcher. (see SDEN for
details)
However, this patch implements the 2nd possible workaround which sets

This change introduces a new NPM run script to automatically generate
the release changelog, as well as bump version numbers across the
code-base and create the release tag.
This script runs [Standard Version] to execute this, which is a tool
designed around automating substantial parts of the release process.
This can be done by running:
npm run release -- [<standard-version args>]
Standard Version expects the project to adhere to the [Semantic
Versioning] convention which TF-A does not, so you may need to specify
the version manually, e.g.:
npm run release -- --release-as 2.6.0
Individual steps of the release process may also be skipped at-will,
which may be necessary when, for example, tweaking the changelog:
npm run release -- --skip.commit --skip.tag
Standard Version is configured by the `.versionrc.js` file, which
contains information about the Conventional Commits types and scopes
used by the project, and how they map to the changelog.
To maintain continuity with the existing changelog style - at least to
the extent possible in the move from manual to automatic creation - a
customized changelog template has been introduced, based on the
Conventional Commits template provided by Standard Version.
This template package extends the Conventional Commits template package
by introducing support for parsing the Conventional Commits scopes into
changelog sections, similarly to how they were previously organized.
[Standard Version]:
https://github.com/conventional-changelog/standard-version

Recently some of our dependencies' dependencies have come into conflict

The existing `requirements.txt` file is now automatically generated by
the `pip-compile` tool - part of the pip-tools package - and ensures
that our dependency tree is also pinned. This is a manual process at
present, but our dependencies are updated infrequently enough that it's
not introducing any major overhead.

This patch adds two new compile time options to enable SME in TF-A:
ENABLE_SME_FOR_NS and ENABLE_SME_FOR_SWD for use in non-secure and
secure worlds respectively. Setting ENABLE_SME_FOR_NS=1 will enable
SME for non-secure worlds and trap SME, SVE, and FPU/SIMD instructions
in secure context. Setting ENABLE_SME_FOR_SWD=1 will disable these
traps, but support for SME context management does not yet exist in
SPM so building with SPD=spmd will fail.
The existing ENABLE_SVE_FOR_NS and ENABLE_SVE_FOR_SWD options cannot
be used with SME as it is a superset of SVE and will enable SVE and
FPU/SIMD along with SME.

MPMM - the Maximum Power Mitigation Mechanism - is an optional
microarchitectural feature present on some Armv9-A cores, introduced
with the Cortex-X2, Cortex-A710 and Cortex-A510 cores.
MPMM allows the SoC firmware to detect and limit high activity events
to assist in SoC processor power domain dynamic power budgeting and
limit the triggering of whole-rail (i.e. clock chopping) responses to
overcurrent conditions.
This feature is enabled via the `ENABLE_MPMM` build option.
Configuration can be done via FCONF by enabling `ENABLE_MPMM_FCONF`, or
by via the plaform-implemented `plat_mpmm_topology` function.

This change makes AMU auxiliary counters configurable on a per-core
basis, controlled by `ENABLE_AMU_AUXILIARY_COUNTERS`.
Auxiliary counters can be described via the `HW_CONFIG` device tree if
the `ENABLE_AMU_FCONF` build option is enabled, or the platform must
otherwise implement the `plat_amu_topology` function.
A new phandle property for `cpu` nodes (`amu`) has been introduced to
the `HW_CONFIG` specification to allow CPUs to describe the view of
their own AMU:
```
cpu0: cpu@0 {
...
amu = <&cpu0_amu>;
};
```
Multiple cores may share an `amu` handle if they implement the
same set of auxiliary counters.
AMU counters are described for one or more AMUs through the use of a new
`amus` node:
```
amus {
cpu0_amu: amu-0 {
#address-cells = <1>;
#size-cells = <0>;
counter@0 {
reg = <0>;
enable-at-el3;
};
counter@n {
reg = <n>;
...
};
};
};
```
This structure describes the **auxiliary** (group 1) AMU counters.
Architected counters have architecturally-defined behaviour, and as
such do not require DTB entries.
These `counter` nodes support two properties:
- The `reg` property represents the counter register index.
- The presence of the `enable-at-el3` property determines whether
the firmware should enable the counter prior to exiting EL3.

This change reduces preprocessor dependencies on the
`AMU_GROUP1_NR_COUNTERS` and `AMU_GROUP1_COUNTERS_MASK` definitions, as
these values will eventually be discovered dynamically.
In their stead, we introduce the `ENABLE_AMU_AUXILIARY_COUNTERS` build
option, which will enable support for dynamically detecting and
enabling auxiliary AMU counters.
This substantially reduces the amount of memory used by platforms that
know ahead of time that they do not have any auxiliary AMU counters.
