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.

This change refactors the SPMD to setup SPMC CPU contexts once and early
from spmd_spmc_init (single call to cm_setup_context rather than on each
and every warm boot).
Pass the core linear ID through a GP register as an implementation
defined behavior helping FF-A adoption to legacy TOSes (essentially
when secure virtualization is not used).
A first version of this change was originally submitted by Lukas [1].
Pasting below the original justification:
Our TEE, Kinibi, is used to receive the core linear ID in the x3
register of booting secondary cores.
This patch is necessary to bring up secondary cores with Kinibi as an
SPMC in SEL1.
In Kinibi, the TEE is mostly platform-independent and all platform-
specifics like topology is concentrated in TF-A of our customers.
That is why we don't have the MPIDR - linear ID mapping in Kinibi.
We need the correct linear ID to program the GICv2 target register,
for example in power management case.
It is not needed on GICv3/v4, because of using a fixed mapping from
MPIDR to ICDIPTR/GICD_ITARGETSRn register.
For debug and power management purpose, we also want a unified view to
linear id between Linux and the TEE.
E.g. to disable a core, to see what cores are printing a trace /
an event.
In the past, Kinibi had several other designs, but the complexity was
getting out of control:
* Platform-specific assembler macros in the kernel.
* A per-core SMC from Linux to tell the linear ID after the boot.
* With DynamiQ, it seems SIPs were playing with MPIDR register values,
reusing them between cores and changing them during boot.

Neoverse N2 erratum 2067956 is a Cat B erratum that applies to
revision r0p0 and is still open. The workaround is to set
CPUACTLR_EL1[46] to force L2 tag ECC inline correction mode.
This workaround works on revision r0p0.

The FMU is part of the GIC Distributor (GICD) component. It implements
the following functionality in GIC-600AE:
* Provides software the means to enable or disable a Safety Mechanism
within a GIC block.
* Receives error signaling from all Safety Mechanisms within other GIC
blocks.
* Maintains error records for each GIC block, for software inspection
and provides information on the source of the error.
* Retains error records across functional reset.
* Enables software error recovery testing by providing error injection
capabilities in a Safety Mechanism.
This patch introduces support to enable error detection for all safety
mechanisms provided by the FMU. Platforms are expected to invoke the
initialization function during cold boot.
The support for the FMU is guarded by the GICV3_SUPPORT_GIC600AE_FMU
makefile variable. The default value of this variable is '0'.

This patch adds the necessary files to support
the SolidRun CN913X CEx7 Evaluation Board.
Because the DRAM connectivity and SerDes settings
is shared with the CN913X DB - reuse relevant
board-specific files.

It was enabled in commit 3c7dcdac5c ("marvell/a3700: Prevent SError
accessing PCIe link while it is down") with a workaround for a bug found
in U-Boot and Linux kernel driver pci-aardvark.c (PCIe controller driver
for Armada 37xx SoC) which results in SError interrupt caused by AXI
SLVERR on external access (syndrome 0xbf000002) and immediate kernel
panic.
Now when proper patches are in both U-Boot and Linux kernel projects,
this workaround in TF-A should not have to be enabled by default
anymore as it has unwanted side effects like propagating all external
aborts, including non-fatal/correctable into EL3 and making them as
fatal which cause immediate abort.
Add documentation for HANDLE_EA_EL3_FIRST build option into Marvell
Armada build section.

Cortex A78 AE erratum 1941500 is a Cat B erratum that applies
to revisions <= r0p1. It is still open.
This erratum is avoided by by setting CPUECTLR_EL1[8] to 1.
There is a small performance cost (<0.5%) for setting this
bit.
