Chris Kay 35cc497d0a docs(prerequisites): update to Node.js v16
Updates the Node.js version installed by the prerequisite instructions
from v14 to v16, which is the latest LTS release.

The instructions for installing the Node Version Manager (NVM) have
also been updated for v0.39.0 (previously v0.38.0).

Chris Kay a539c77185 build(docs): pin Python dependencies
Recently some of our dependencies' dependencies have come into conflict
and are now causing errors when trying to install the Python
requirements. This change introduces `requirements.in` - a list of our
own direct dependencies, and pins them to specific versions.

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.

johpow01 dc78e62d80 feat(sme): enable SME functionality
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.

Chris Kay 68120783d6 feat(mpmm): add support for MPMM
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.

Chris Kay 742ca2307f feat(amu): enable per-core AMU auxiliary counters
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.

Chris Kay 1fd685a74d refactor(amu): conditionally compile auxiliary counter support
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.

Chris Kay 6c8dda19e5 refactor(amu)!: remove `PLAT_AMU_GROUP1_COUNTERS_MASK`
With the introduction of MPMM, the auxiliary AMU counter logic requires
refactoring to move away from a single platform-defined group 1 counter
mask in order to support microarchitectural (per-core) group 1 counters.

BREAKING CHANGE: The `PLAT_AMU_GROUP1_COUNTERS_MASK` platform definition
has been removed. Platforms should specify per-core AMU counter masks
via FCONF or a platform-specific mechanism going forward.

I expect more boards with multiple DRAM sizes to be

Zelalem Aweke 5b18de09e8 feat(rme): add ENABLE_RME build option and support for RMM image
The changes include:

- A new build option (ENABLE_RME) to enable FEAT_RME

- New image called RMM. RMM is R-EL2 firmware that manages Realms.
  When building TF-A, a path to RMM image can be specified using
  the "RMM" build flag. If RMM image is not provided, TRP is built
  by default and used as RMM image.

- Support for RMM image in fiptool

nayanpatel-arm b36fe21243 errata: workaround for Cortex-A78 erratum 2132060
Cortex-A78 erratum 2132060 is a Cat B erratum that applies to
revisions r0p0, r1p0, r1p1, and r1p2 of CPU. It is still open.
The workaround is to write the value 2'b11 to the PF_MODE bits
in the CPUECTLR_EL1 register which will place the data prefetcher
in the most conservative mode instead of disabling it.
