Align the Corstone1000 Ethos-U85 device tree to match the upstream
bindings used by the in-tree Ethos-U DRM accel driver.
- Rework the Corstone1000 U-Boot patch to replace the legacy arm,ethosu-direct
node with an upstream-style Ethos-U85 node (arm,ethos-u85), add the
required clocks/clock-names, and switch the SRAM description to
mmio-sram.
- Drop meta-ethos specific properties (reserved-memory/dma-ranges,
/region-cfgs/mem-config) from the U-Boot DT.
- Enable required kernel options for the in-tree driver and SRAM provider:
- CONFIG_SRAM
- CONFIG_DRM
- CONFIG_DRM_ACCEL
- CONFIG_DRM_ACCEL_ARM_ETHOSU

Trusted Services has introduced a Firmware TPM (fTPM) secure partition.
This change enables building and deploying the fTPM SP through meta-arm.
The secure partition is based on the TPM2 reference implementation,
msp-tpm20-ref, which has been patched to use MbedTLS as its
crypto backend and psa-its for non-volatile storage.

* Set Linux kernel preferred version for Corstone-1000 to 6.18
* Update Corstone-1000 user guide.
* Recent kernel versions removed the deprecated CONFIG_LIBCRC32C
Kconfig symbol as part of the CRC library cleanup.
Replace CONFIG_LIBCRC32C with CONFIG_CRC32, which provides the
generic CRC32/CRC32C library support used by in-kernel consumers.
* The ext3 driver was removed historically and ext4 carries
compatibility for ext3 on-disk format.
* Amend External System patch to adhere to Kernel v6.18 RemoteProc
API.
* Add #address-cells and #size-cells parameters to ethosu dts node

Enable the Corstone‑1000 Cortex‑A320 variant by:
- Introduce `machine/include/corstone1000-a320.inc` to configure the
default Ethos‑U MAC count when `cortexa320` is in MACHINE_FEATURES,
and allow override via `ETHOSU_NUM_MACS`.
- Add a KAS profile at `kas/corstone1000-a320.yml` for Cortex‑A320
FVP-based builds.
- Extend corstone1000.inc to detect MACHINE_FEATURES (cortexa320) and
pull in the matching tune-<core>.inc (default still Cortex-A35).
- Add the `meta-ethos` layer as a dependency of `meta-arm-bsp` for
Cortex‑A320 builds and define a new KMachine override to pull in
the Ethos‑U driver recipe.
- In `conf/machine/corstone1000-fvp.conf`, inspect `MACHINE_FEATURES`
and set `FVP_EXE` to `FVP_Corstone-1000_with_Cortex-A320` when
`cortexa320` is enabled, otherwise fall back to `FVP_Corstone-1000`.
- In `recipes-devtools/fvp/fvp-corstone1000.bb`, add a
`SRC_URI:cortexa320` entry (with checksums) for the Cortex‑A320 FVP
build archive.
- Disable the rootfs CPIO file compression so it is not compressed
twice when bundled with the kernel

Set the Upstream-Status to Denied because the community suggests a different design
The external system implementation in Corstone-1000 is user-defined.
In the implementation provided by he FPGA board and by the FVP, the
Cortex-A35 (Linux) can not access the memory of the external system (Cortex-M3).
So, Linux can not load the external system firmware and can not communicate
with the external system using Rpmsg over remoteproc subsystem. The reason is Rpmsg
needs vrings memory buffers to be shared between both cores.
The community prefers that the HW is updated with memory sharing before they
consider merging the remoteproc driver.
We reached the agreement that we will split the work in two parts:
Part 1: Writing an SSE-710 reset controller driver
Part 2: Corstone-1000 remoteproc driver
Part 1 is doable and we will be working on it.
Part 2 is waiting for the FPGA upgrade with the memory sharing feature.

When booting, the tee driver from kernel side
invokes a yielding call to OP-TEE, which gets
stuck because OP-TEE never sends Done response:
OPTEE_FFA_YIELDING_CALL_RETURN_DONE
This issue was previously resolved by introducing
an inappropriate patch to the kernel with 1 ms delay
in ffa_msg_send_direct_req.
Further investigation proved that OP-TEE doesn't
get enough processing time and is constantly interrupted
by the kernel requests. To remove this patch, TF-A logging
level is lowered to default (40 in debug builds and
20 in release builds), which eliminates the time consumed
previously by TF-A VERBOSE logs (giving OP-TEE more
processing time).

Arm generic timer provides different timers for different exception
levels and different secure states. Because Armv8-R AArch64 has secure
state only, the valid timer for hypervisor in EL2 is secure hypervisor
physical timer. But for platform fvp-baser-aemv8r64, before FVP 11.18,
the secure hypervisor physical timer could not work well in EL2, so we
had been using Non-secure physical timer in EL2 for hypervisor as a
workaround.
Since secure hypervisor physical timer issue has been fixed from FVP
11.18, we can use this correct timer in EL2 for hypervisor now. So we
update the device tree timer node to use secure hypervisor physical
timer interrupt for hypervisor.

The 64-bit fvp-base machine uses the upstream fvp-base-recv devicetree,
but fvp-base-arm32 was accidentally using the old
fvp-base-gicv3-psci-custom that we patch into the kernel.
As the only difference between these platforms at a "hardware" level is
whether the cores boot in 32- or 64-bit mode, they should both use
fvp-base-revc.
This isn't trivial as devicetree files need to be under the correct
arch/ directory, so we need to symlink into arch/arm the right files
from arch/arm64.
This has several improvements, but primarily virtio networking works so
we can now use testimage with fvp-base-arm32.

This commit introduces a new kernel patch that aligns the FF-A
versions checks according to the FF-A specification v1.0.
Without this fix, the FF-A bus fails to initialize when the FF-A
framework is version 1.1 (comes with the latest TF-A).
The bus driver which is v1.0 rejects the framework v1.1 despite
the fact they are compatible according to the specification.
This kernel patch changes the logic of the version checking based on
