This patch enables support of FEAT_FPMR by enabling access
to FPMR register. It achieves it by setting the EnFPM bit of
SCR_EL3. This feature is currently enabled for NS world only.

This new update to the LTS branch of MbedTLS provides
the fix for a buffer underrun vulnerability. TF-A does
not use the previously vulnerable functions
`mbedtls_pk_write_key_der` or `mbedtls_pk_write_key_pem`.
Full patch notes to this MbedTLS update can be found at
https://github.com/Mbed-TLS/mbedtls/releases/tag/mbedtls-3.6.2.

According to Platform Initialization (PI) Specification [1] and
discussion on edk2 mailing list [2],
StandaloneMm shouldn't create Hob but it should be passed from TF-A.
IOW, TF-A should pass boot information via HOB list to initialise
StandaloneMm properly.
And this HOB lists could be delivered via
- SPM_MM: Transfer List according to the firmware handoff spec[3]
- FF-A v1.1 >= : FF-A boot protocol.
This patch introduces a TF-A HOB creation library and
some of definitions which StandaloneMm requires to boot.

This small change removes the footnote from Poetry that it is only used
for building documentation, as it is now used for some of the Python
tooling in the repository from the build system.
Additionally, add a link to the official installation guide for Poetry.

* Additionally it updates the existing details on the

Armv8.6 introduced the FEAT_LS64 extension, which provides a 64 *byte*
store instruction. A related instruction is ST64BV0, which will replace
the lowest 32 bits of the data with a value taken from the ACCDATA_EL1
system register (so that EL0 cannot alter them).
Using that ST64BV0 instruction and accessing the ACCDATA_EL1 system
register is guarded by two SCR_EL3 bits, which we should set to avoid a
trap into EL3, when lower ELs use one of those.
Add the required bits and pieces to make this feature usable:
- Add the ENABLE_FEAT_LS64_ACCDATA build option (defaulting to 0).
- Add the CPUID and SCR_EL3 bit definitions associated with FEAT_LS64.
- Add a feature check to check for the existing four variants of the
LS64 feature and detect future extensions.
- Add code to save and restore the ACCDATA_EL1 register on
secure/non-secure context switches.
- Enable the feature with runtime detection for FVP and Arm FPGA.
Please note that the *basic* FEAT_LS64 feature does not feature any trap
bits, it's only the addition of the ACCDATA_EL1 system register that
adds these traps and the SCR_EL3 bits.

Add documentation for the feature where EL3 can be used to sign realm
attestation token requests using RMM_EL3_TOKEN_SIGN command.
This patch also adds documentation for the RMM_EL3_FEATURES features
command that can be used to discover support for features such as
RMM_EL3_TOKEN_SIGN.

This patch disables trapping to EL3 when the FEAT_D128
specific registers are accessed by setting the SCR_EL3.D128En bit.
If FEAT_D128 is implemented, then FEAT_SYSREG128 is implemented.
With FEAT_SYSREG128 certain system registers are treated as 128-bit,
so we should be context saving and restoring 128-bits instead of 64-bit
when FEAT_D128 is enabled.
FEAT_SYSREG128 adds support for MRRS and MSRR instruction which
helps us to read write to 128-bit system register.
Refer to Arm Architecture Manual for further details.
Change the FVP platform to default to handling this as a dynamic option
so the right decision can be made by the code at runtime.

Arm has made the strategic decision to deprecate the TC2 platform. As
a result, software development and the creation of fast models for TC2
have been officially discontinued. The TC2 platform, now considered
obsolete, has been succeeded by the TC3 and TC4 platforms. Notably,
both TC3 and TC4 are already integrated into TF-A, with TC3 included
in the CI repository. Work to add CI support for TC4 is currently in
progress.
