From QEMU change:
> In previous versions of the Arm architecture, the frequency of the
> generic timers as reported in CNTFRQ_EL0 could be any IMPDEF value,
> and for QEMU we picked 62.5MHz, giving a timer tick period of 16ns.
> In Armv8.6, the architecture standardized this frequency to 1GHz.
This change stops TF-A from hardcoding 62.5MHz frequency. Instead value
stored in CNTFRQ_EL0 would be used. As a result we get 62.5MHz on older
cores and 1GHz on newer ones.

Currently, TF-A supports three states for feature flags:
0: FEAT_DISABLED
1: FEAT_STATE_ALWAYS ( for fixed/real platforms)
2: FEAT_STATE_CHECK ( for configurable platforms)
to meet the feature detection requirements dynamically, mainly
targetting configurable/Fixed Virtual platforms.
With this mechanism in place, we are refactoring all the existing
feature flags to the FEAT_STATE_CHECK option(=2), including
FEAT_SVE explicitly for FVPs.
SVE Patch Reference:
https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/19888/25
This newly introduced change, breaks the existing behaviour especially
for virtual platforms, who have set the ENABLE_SVE_FOR_NS flag to 1.
Moving ahead, we advise the platforms to take the following steps while
enabling the features:
1. If the platform is configurable (virtual), and want to ensure feature
detection happens dynamically at runtime, set the build flags to
FEAT_STATE_CHECK(=2).
2. For real(fixed) platforms, depending on the features supported by the
hardware and platform wants to enable it, platforms could set build
flags to FEAT_STATE_ALWAYS(=1).
(Note: Only the non-secure world enablement related build flags have
been refactored to take the values within 0 to 2. As earlier Secure
world enablement flags will still remain boolean.)
Henceforth, in order to keep it aligned with this tri-state mechanism,
changing the qemu platform default to the now supported dynamic
option(=2), so the right decision can be made by the code at runtime.

Some of our specialized sections are not prefixed with the conventional
period. The compiler uses input section names to derive certain other
section names (e.g. `.rela.text`, `.relacpu_ops`), and these can be
difficult to select in linker scripts when there is a lack of a
delimiter.
This change introduces the period prefix to all specialized section
names.
BREAKING-CHANGE: All input and output linker section names have been
prefixed with the period character, e.g. `cpu_ops` -> `.cpu_ops`.

Commit 337ff4f1dd enabled SVE/SME for
qemu platform. Let do the same for qemu-sbsa one too.
With this change I can boot Debian 'bookworm' installed using Max cpu.
Info from referenced commit:
Starting with QEMU v3.1.0 (Dec 2018), QEMU's TCG emulation engine supports
the SVE architecture extension. In QEMU v7.1.0 (Aug 2022) it also gained
SME support.
As it stands today, running TF-A under QEMU with "-cpu max" makes Linux
hang, because SME and SVE accesses trap to EL3, but are never handled
there. This is because the Linux kernel sees the SVE or SME feature bits,
and assumes firmware has enabled the feature for lower exception levels.
This requirement is described in the Linux kernel booting protocol.
Enable those features in the TF-A build, so that BL31 does the proper
EL3 setup to make the feature usable in non-secure world.
We check the actual feature bits before accessing SVE or SME registers,
so this is safe even for older QEMU version or when not running with
-cpu max. As SVE and SME are AArch64 features only, do not enable them
when building for AArch32.

This patch adds mapping for secure FLASH0 for qemu/virt and
qemu/qemu_sbsa platforms. This change is targeted for sbsa but since both
platforms share common code, changes in common defines was necessary.
For qemu_sbsa, this patch adds necessary mapping in order to boot without
semi-hosting from secure FLASH0. EFI need to stay in FLASH1 (share it with
variables) since it need to "run in place" in non secure domain. Changes
for this are under RFC at edk2-platforms mailing list:
https://patches.linaro.org/patch/171327/
(edk2-platforms/Platform/Qemu/SbsaQemu/SbsaQemu.dsc).
In docs qemu/virt is described as using semi-hosting, therefore this change
should be orthogonal to existing assumptions while giving possibility to
store both bl1 and fip in FLASH0 at some point (additional changes required
for that).
