fix(cpus): workaround for Cortex-A710 erratum 2291219
Cortex-A710 erratum 2291219 is a Cat B erratum that applies to revisions

fix(aarch64): make AArch64 FGT feature detection more robust
The ARMv8 ARM says about the values in the ID register scheme:
==== D17.1.3 Principles of the ID scheme for fields in ID registers ===
The ID fields, which are either signed or unsigned, use increasing
numerical values to indicate increases in functionality. Therefore,
if a value of 0x1 indicates the presence of some instructions, then
the value 0x2 will indicate the presence of those instructions plus
some additional instructions or functionality. This means software
can be written in the form:
if (value >= number) {
// do something that relies on the value of the feature
}
=======================================================================
So to check for the presence of a certain architecture feature, we
should not check against a certain specific value, as it's done right
now in several cases.
Relax the test for Fine Grained Trapping (FGT) to just check against
the field being 0 or not.
This fixes TF-A crashing due to an unhandled exception, when running a
Linux kernel on an FVP enabling ARMv8.9 features. The value of
ID_AA64MMFR0_EL1.FGT went from 0b0001 to 0b0010 there.

service exposed by BL31 to lower exception levels. We are not there

Delegated attestation is currently made dependent on measured boot
support. This dependency is not at the source code level (attestation
code does not invoke any measured boot interfaces) but it is rather a
logical dependency: attestation without boot measurements is not very
useful...

refactor(fvp): fdts: consolidate GICv3 base FVP DT files
The GICv2 and GICv3 version of the FVP DT files are unnecessarily split,
as the common part of the peripherals is the same: it's literally just
the interrupt controller node that is different.
To facilitate a unification, refactor the DT include files to explicitly
include a snippet with just the GICv3 description, and a generic base DT
file for the rest. This generic file can then be reused by the GICv2
versions later.
Since we can only have a /memreserve/ entry *before* any DT nodes, move
that line to each file, to allow including the GIC DT file separately.

feat(fvp): dts: drop 32-bit .dts files
Conceptually the DT is a hardware description, as such it's independent
from the instruction set that a DT client uses. So having separate DTs
for aarch32 and aarch64 does not make sense and is not needed.
Probably due to historic reasons (a Linux bug fixed in 2016 with Linux
commit ba6dea4f7ced, in Linux v4.8) the CPU reg property was using a
different size between aarch64 and aarch32, even though the size of it
is solely governed by the parent's #address-cells property.
Consolidate this to be always 2, and always use two cells to describe
the CPU's MPIDR register.
This removes the last difference of the -aarch32 versions of the FVP
DT files, so just remove all of them. The respective versions without
that suffix can now be used with AArch32 DT clients as well.
Also remove the respective part in the documentation.

For no real reason we were shipping two separate DT include files for the
base FVP motherboard peripherals, one for aarch32, one for aarch64.
There is no difference in the hardware description when using a
different instruction set, and the diff between the two files was about
a missing interrupt map for the 64-bit DT files.
Consolidate the situation by just using a single motherboard .dtsi file,
which relies on an interrupt map by the including files.
Provide that map in the two files where it was missing before, and
change the filenames to let all users include the same file now.
