Neoverse-V1 erratum 2108267 is a Cat B erratum that applies to
revisions r0p0, r1p0, and r1p1 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.

Add support for Arm Ethos-N NPU multi-device.
The device tree parsing currently only supports one NPU device with
multiple cores. To be able to support multi-device NPU configurations
this patch adds support for having multiple NPU devices in the device
tree.
To be able to support multiple NPU devices in the SMC API, it has been
changed in an incompatible way so the API version has been bumped.

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'.

At the moment we have a GIC_ENABLE_V4_EXTN build time variable to
determine whether the GIC interrupt controller is compliant to version
4.0 of the spec or not. This just changes the number of 64K MMIO pages
we expect per redistributor.
To support firmware builds which run on variable systems (emulators,
fast model or FPGAs), let's make this decision at runtime.
The GIC specification provides several architected flags to learn the
size of the MMIO frame per redistributor, we use GICR_TYPER[VLPI] here.
Provide a (static inline) function to return the size of each
redistributor.
We keep the GIC_ENABLE_V4_EXTN build time variable around, but change
its meaning to enable this autodetection code. Systems not defining this
rely on a "pure" GICv3 (as before), but platforms setting it to "1" can
now deal with both configurations.

The UART code for the A3K platform assumes that UART parent clock rate
is always 25 MHz. This is incorrect, because the xtal clock can also run
at 40 MHz (this is board specific).
The frequency of the xtal clock is determined by a value on a strapping
pin during SOC reset. The code to determine this frequency is already in
A3K's comphy driver.
Move the get_ref_clk() function from the comphy driver to a separate
file and use it for UART parent clock rate determination.

NOTE: Breaking change to the way UUIDs are stored in the DT
Currently, UUIDs are stored in the device tree as
sequences of 4 integers. There is a mismatch in endianness
between the way UUIDs are represented in memory and the way
they are parsed from the device tree. As a result, we must either
store the UUIDs in little-endian format in the DT (which means
that they do not match up with their string representations)
or perform endianness conversion after parsing them.
Currently, TF-A chooses the second option, with unwieldy
endianness-conversion taking place after reading a UUID.
To fix this problem, and to make it convenient to copy and
paste UUIDs from other tools, change to store UUIDs in string
format, using a new wrapper function to parse them from the
device tree.

The filters parameter passed to tzc400_configure_region() is supposed
to be filter bit flag without bit shift, so the macros
TZC_400_REGION_ATTR_FILTER_BIT and TZC_400_REGION_ATTR_FILTER_BIT_ALL
should always construct the value without any shift.
It is not a functional issue for TZC_REGION_ATTR_F_EN_SHIFT is lucky
to be 0.

This adds the TRNG Firmware Interface Service to the standard
service dispatcher. This includes a method for dispatching entropy
requests to platforms and includes an entropy pool implementation to
avoid dropping any entropy requested from the platform.

The coding guidelines[1] in TF-A forbid the use of ato*() functions
in favour of strto*(). However, the TF-A libc does not provide an
implementation of strto*(), making this rule impossible to satisfy.
Also made small changes to fit into TF-A project. Added the source

For SoCs which do not implement RAS, use DSB as a barrier to
synchronize pending external aborts at the entry and exit of
exception handlers. This is needed to isolate the SErrors to
appropriate context.
However, this introduces an unintended side effect as discussed
in the https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/3440
A summary of the side effect and a quick workaround is provided as
part of this patch and summarized here:
The explicit DSB at the entry of various exception vectors in BL31
for handling exceptions from lower ELs can inadvertently trigger an
SError exception in EL3 due to pending asyncrhonouus aborts in lower
ELs. This will end up being handled by serror_sp_elx in EL3 which will
ultimately panic and die.
The way to workaround is to update a flag to indicate if the exception
truly came from EL3. This flag is allocated in the cpu_context
structure. This is not a bullet proof solution to the problem at hand
because we assume the instructions following "isb" that help to update
the flag (lines 100-102 & 139-141) execute without causing further
exceptions.

This patch does not change code, it only updates comments and macro name
for 6th bit of Status Register. So TF-A binary stay same.
6th bit of the Status Register is named TX EMPTY and is set to 1 when both
Transmitter Holding Register (THR) or Transmitter Shift Register (TSR) are
empty. It is when all characters were already transmitted.
There is also TX FIFO EMPTY bit in the Status Register which is set to 1
only when THR is empty.
In both console_a3700_core_init() and console_a3700_core_flush() functions
we should wait until both THR and TSR are empty therefore we should check
6th bit of the Status Register.
So current code is correct, just had misleading macro names and comments.
This change fixes this "documentation" issue, fixes macro name for 6th bit
of the Status Register and also updates comments.

Cortex A78 erratum 1951500 is a Cat B erratum that applies to revisions
r0p0, r1p0, and r1p1. The workaround is to insert a DMB ST before
acquire atomic instructions without release semantics. This workaround
works on revisions r1p0 and r1p1, in r0p0 there is no workaround.

Cortex A78 erratum 1941498 is a Cat B erratum that applies to revisions
r0p0, r1p0, and r1p1. The workaround is to set bit 8 in the ECTLR_EL1
register, there is a small performance cost (<0.5%) for setting this bit.

Write char if fifo is empty. If this is done like this all chars are
printed. Because origin code just put that chars to fifo and in case of
reset messages were missing.
Before this change chars are put to fifo and only check before adding if
fifo is full. The patch is changing this logic that it is adding char only
when fifo is empty to make sure that in case of reset (by another SW for
example) all chars are printed. Maybe one char can be missed but for IP
itself it is much easier to send just one char compare to full fifo.

This gives the rich OS the flexibility to choose between I2C and RSB
communication. Since a runtime address can only be assigned once after
entering RSB mode, it also lets the rich OS choose any runtime address.

If FEAT_PMUv3 is implemented and PMEVTYPER<n>(_EL0).MT bit is implemented
as well, it is possible to control whether PMU counters take into account
events happening on other threads.
If FEAT_MTPMU is implemented, EL3 (or EL2) can override the MT bit
leaving it to effective state of 0 regardless of any write to it.
This patch introduces the DISABLE_MTPMU flag, which allows to diable
multithread event count from EL3 (or EL2). The flag is disabled
by default so the behavior is consistent with those architectures
that do not implement FEAT_MTPMU.
