-Some TS recipes support yocto variables to set build configuration. These variables can be set in .conf files (machine
-specific or local.conf), or .bbappend files. 
-
-SmmGW SP recipe supports the following configuration variables
-
-| Variable name         | Type | Description                                                                                            |
-|-----------------------|------|--------------------------------------------------------------------------------------------------------|
-| SMMGW_AUTH_VAR        | Bool | Enable Authenticated variable support                                                                  |
-| SMMGW_INTERNAL_CRYPTO | Bool | Use MbedTLS build into SmmGW for authentication related crypto operations. Depends on SMMGW_AUTH_VAR=1 |

-Known Issues or Limitations
---------------------------
-
- - Crypto isolation is not supported in the Secure world of Corstone-1000. Additionally, clients in
-   the Normal world are not isolated from one another.Therefore, if an end user wants to add a new
-   Secure Partition (SP) (such as a software TPM) that accesses the Crypto service via the SE-Proxy,
-   they are responsible for implementing their own isolation mechanisms to ensure proper security boundaries.
- - DSTREAM debug probe may experience unreliable USB connectivity when used with Arm DS for secure debug.
-   This issue is under active investigation, and we are working to identify and resolve compatibility issues in a future update.
-   As a more stable alternative, the ULINKpro debug probe is recommended for use with Corstone-1000 in secure debug scenarios.

-The Corstone-1000 boot uses a `Secure boot <arm-developer-secureboot-website_>`__ chain process
-where an already authenticated image verifies and loads the following software in the chain.

+It is a lengthy chain to boot the software on Corstone-1000. On power on,
+the Secure Enclave starts executing BL1_1 code from the ROM which is the RoT
+of the device. The BL1_1 is the immutable bootloader of the system, it handles
+the provisioning on the first boot, hardware initialization and verification
+of the next stage.

-TF-M BL1_1
-==========
+The BL1_2 code, hashes and keys are written into the OTP during the provisioning.
+The next bootstage is the BL1_2 which is copied from the OTP into the RAM. The
+BL1_1 also compares the BL1_2 hash with the hash saved to the OTP. The BL1_2
+verifies and transfers control to the next bootstage which is the BL2. During the
+verification, the BL1_2 compares the BL2 image's computed hash with the BL2 hash in
+the OTP. The BL2 is MCUBoot in the system. BL2 can provision additional keys on the
+first boot and it authenticates the initial bootloader of the host (Host TF-A BL2)
+and TF-M by checking the signatures of the images.
+The MCUBoot handles the image verification the following way:

-On power-up, the Secure Enclave begins execution from TF-M BL1_1, which resides in ROM and serves as
-the Root of Trust (RoT) for the device.
-
-TF-M BL1_1 is the immutable bootloader and is responsible for:
-
- Provisioning the device during the first boot
- Performing hardware initialization
- Verifying the integrity and authenticity of the next stage in the boot chain
-
-At boot time, TF-M BL1_1:
-
- Copies the TF-M BL1_2 image from OTP to RAM.
- Verifies the integrity of BL1_2 by comparing its computed hash with the hash stored in OTP.
-
-TF-M BL1_2
-==========
-
-During provisioning, the TF-M BL1_2 binary, along with its hashes and cryptographic keys, is stored
-in One-Time Programmable (OTP) memory.
-
-Once verified, TF-M BL1_2:
-
- Takes control and verifies the next stage in the boot chain, which is TF-M BL2.
- Computes the hash of the BL2 image and compares it with the BL2 hash stored in OTP to ensure
-  integrity before transferring execution to BL2.
-
-.. note::
-
-    The TF-M BL1 design details can be found in the `TF-M design documents <trusted-firmware-m-bl1-website_>`_.
-
-    .. important::
-
-        Corstone-1000 has some differences compared to this design due to memory (OTP/ROM)
-        limitations:
-
-        - BL1_1 code size is larger than needed because it handles most of the hardware initialization instead of the BL1_2.
-        - BL1_2 cannot be updated during provisioning time because the provisioning bundle that contains its code is located in the ROM.
-        - BL1_2 does not use the post-quantum LMS verification.
-        - BL2 cannot be updated because it is verified by comparing the computed hash to the hash stored in the OTP.
-
-TF-M BL2
-========
-
-In this system, TF-M BL2 refers to MCUBoot.
-
-On the first boot, MCUBoot can provision additional cryptographic keys. It is responsible for authenticating both:
-
- TF-M (Trusted Firmware-M), and
- The initial bootloader of the Host system, `Trusted Firmware-A (TF-A) BL2 <trusted-firmware-a-bl2-website_>`__
-
-This authentication is done by verifying the digital signatures of the respective images.
-
-MCUBoot performs image verification in the following steps:
-
-#. Load the image from non-volatile memory into RAM.
-#. Validate the image's signature using the corresponding public key.
-
-.. note::
-
-   The public key present in the image header is validated by comparing with the hash.
-   Depending on the image, the hash of the public key is either stored in the OTP or part
-   of the software which is being already verified in the previous stages.

+The Corstone-1000 has some differences compared to this design due to memory (OTP/ROM)
+limitations:

-Host System Authentication
-==========================
+- The provisioning bundle that contains the BL1_2 code is located in the ROM.
+  This means the BL1_2 cannot be updated during provisioning time.
+- The BL1_1 handles most of the hardware initialization instead of the BL1_2. This
+  results in a bigger BL1_1 code size than needed.
+- The BL1_2 does not use the post-quantum LMS verification. The BL2 is verified by
+  comparing the computed hash to the hash which is stored in the OTP. This means the
+  BL2 is not updatable.

-The Host system follows the boot standard defined in the `Trusted Board Boot Requirements Client <trusted-board-boot-requirements-client-pdf_>`__
-to authenticate the Secure and Non-secure software.
-
-The `Firmware Image Package (FIP) <trusted-firmware-a-fip-guide_>`__ packs bootloader images and
-other payloads into a single archive.
-

- AP Secure Payload, BL32 image
- AP Normal world firmware -U-boot, BL33 image
- Trusted OS Firmware configuration file used by Trusted OS (BL32), TOS_FW_CONFIG
- Key certificates
- Content certificates
-
-
-To load and validate TF-A BL2, TF-M BL2 first parses the GUID Partition Table (GPT)
-to locate the FIP. It then determines the offset of TF-A BL2 within the FIP.
-
-.. note::
-
-    TF-M does not check the FIP signature, it only checks the TF-A BL2's signature in the FIP.
-
-
-.. important::
-
-    The implicitly trusted components are:
-
-    - A SHA-256 hash of the Root of Trust Public Key (ROTPK) - 
-      For development purposes, a development ROTPK is used and its hash embedded into the TF-A BL2 image.
-      This public key is provided by the TF-A source code.
-    - TF-A BL2 image - it can be trusted because it has been verified by TF-M BL2 before starting TF-A.
-
-
-The remaining components in the Chain of Trust (CoT) are either certificates or bootloader images.
-
-Bootloader Authentication
-------------------------
-
-The FIP contains two types of certificates:
-
- **Content Certificates** - used to store the hash of a bootloader image.
- **Key Certificates** - used to verify public keys used to sign Content Certificates.
-
-The Host system bootloader images are authenticated by computing their hash and comparing it to the corresponding hash found in the Content Certificate.

 Secure Services
 ***************

-Corstone-1000 is unique in offering a secure environment for running trusted workloads.
-While the Host system includes TrustZone technology, the platform also features a hardware-isolated
-Secure Enclave, specifically designed to execute these secure workloads.
-
-In Corstone-1000, essential Secure Services—such as Cryptography, Protected Storage,
-Internal Trusted Storage, and Attestation—are provided through PSA Functional APIs implemented in TF-M.
-
-From the user's perspective, there is no difference when communicating with these services,
-whether they run in the Secure Enclave or in the Secure world of the Host system.
-The diagram below illustrates the data flow for such calls.

-The Secure Enclave Proxy Secure Partition (SE Proxy SP) is a proxy managed by OP-TEE that forwards
-Secure Service calls to the Secure Enclave. This communication uses the `RSE communication protocol <https://tf-m-user-guide.trustedfirmware.org/platform/arm/rse/rse_comms.html>`_.
-While the protocol supports shared memory and MHU interrupts as a doorbell mechanism between cores,
-in Corstone-1000, the entire message is currently transmitted through the MHU channels.
-Corstone-1000 implements Isolation Level 2 using the Cortex-M0+ Memory Protection Unit (MPU).

-Users can define their own secure services to run either in the Host system's Secure World or in
-the Secure Enclave. This choice involves a trade-off between latency and security.
-Services running in the Secure Enclave benefit from strong, hardware-enforced isolation,
-offering higher security but at the cost of increased latency. In contrast, services running in the
-Host Secure World experience lower latency, but rely on TrustZone technology for virtualized isolation,
-which offers comparatively less robust security.

+which is a lightweight serialization of the psa_call() API. It can use shared
+memory and MHU interrupts as a doorbell for communication between two cores
+but currently the whole message is forwarded through the MHU channels in Corstone-1000.
+Corstone-1000 implements isolation level 2. Cortex-M0+ MPU (Memory Protection
+Unit) is used to implement isolation level 2.
+
+For a user to define its own secure service, both the options of the host
+secure world or secure encalve are available. It's a trade-off between
+lower latency vs higher security. Services running on a Secure Enclave are

-PSA Secure Firmware Update

+**********************
+Secure Firmware Update
+**********************

-The Arm Corstone-1000 platform necessitates a robust, secure, and flexible firmware update mechanism
-including partial capsule update to ensure fielded devices can receive critical patches, feature enhancements,
-and security fixes without compromising system integrity. To meet these requirements, we have implemented the
-Platform Security Architecture (PSA) Firmware Update (FWU) framework on Corstone-1000, leveraging Trusted Firmware-M (TF-M)
-for the Secure Enclave, U-Boot as the host-side client on Cortex-A, and the UEFI capsule update mechanism for payload
-encapsulation. This design supports both the Fixed Virtual Platform (FVP) and the Field Programmable Gate Array (FPGA)
-targets, providing consistent behavior across simulation and silicon-based deployments. The Corstone-1000 supports FWU
-which complies with the `Platform Security Firmware Update for the A-profile Arm Architecture <platform-security-fwu-for-a-profile-pdf_>`__
-and `PSA Firmware Update IHI 0093 <psa-firmware-update-ihi-0093-api-reference-website_>`__
-specifications.
+Apart from always booting the authorized images, it is also essential that
+the device only accepts the authorized (signed) images in the firmware update
+process. Corstone-1000 supports OTA (Over the Air) firmware updates and
+follows Platform Security Firmware Update specification (`FWU`_).

-To standardize and streamline capsule creation with multiple FMP payloads, the `EDK2 capsule generation tool <edk2-capsule-generation-tool-repository_>`__
-tool has been integrated into the meta-arm Yocto layer for Corstone‑1000. This integration involves defining
-build rules for generating UEFI capsules as part of the firmware image build process. Configuration parameters
-exposed in the recipe allow developers to specify the number of FMP payloads, target image GUIDs, version numbers etc.
-This capsule ensures that all update payloads conform to the UEFI FMP specification and are ready for
-validation and delivery by U‑Boot.
-
-The FWU solution for Corstone-1000 is composed of three primary domains:
-
- Host System
- Trusted Services intermediary
- Secure Enclave
-
-Each domain has distinct responsibilities and communicates through standardized interfaces.
-
-
-.. image:: images/SystemArchitecturePSAFirmwareUpdate.png
-   :width: 690
-   :alt: SystemArchitecturePSAFirmwareUpdate
-
-On the host side, U-Boot functions as the FWU client and orchestrates the update process from capsule retrieval to

-via Arm FF-A framework. The Trusted-Services SE Proxy secure partition serves as a gateway between the non-secure host
-environment and the Secure Enclave. The `PSA FWU service <ts-psa-fwu-service-website_>`__ running in the Trusted Services
-implementation forwards the data to the Secure Enclave via MHU-based PSA calls. Within the Secure Enclave, the PSA FWU
-Agent, conforming to `PSA Firmware Update IHI 0093 <psa-firmware-update-ihi-0093-api-reference-website_>`__ specification,
-orchestrates the actual flash programming, metadata management, and rollback protection mechanisms. The agent relies on a
-bespoke `shim layer <tfm-shim-layer-website_>`__ to abstract hardware‑specific flash operations and bootloader interactions.
-
-As defined in the specification, the external flash is divided into two banks: one bank holds the
-currently running images, while the other is used to stage new images.
-
-There are four updatable components: **BL2**, **TF-M**, **the FIP** and **the Kernel Image** (the initramfs bundle).
-New images are delivered and accepted in the form of UEFI capsules.
+As standardized into `FWU`_, the external flash is divided into two
+banks of which one bank has currently running images and the other bank is
+used for staging new images.  There are four updatable units, i.e. Secure
+Enclave's BL2 and TF-M, and Host's FIP (Firmware Image Package) and Kernel
+Image (the initramfs bundle). The new images are accepted in the form of a UEFI capsule.

-When a FWU is initiated on Corstone-1000, the following sequence of operations takes place:
+When Firmware update is triggered, U-Boot verifies the capsule by checking the
+capsule signature, version number and size. Then it signals the Secure Enclave
+that can start writing UEFI capsule into the flash.

-#. **Capsule Retrieval and Preparation**
+Once this operation finishes, Secure Enclave resets the entire system.
+The Metadata Block in the flash has the below firmware update state machine.
+TF-M runs an OTA service that is responsible for accepting and updating the
+images in the flash. The communication between the UEFI Capsule update
+subsystem and the OTA service follows the same data path explained above.
+The OTA service writes the new images to the passive bank after successful
+capsule verification. It changes the state of the system to trial state and
+triggers the reset.

-   U-Boot on the host system retrieves the firmware capsule.
-   It validates the capsule header and parses the FMP (Firmware Management Protocol) descriptor list to identify the payloads to be updated.
-
-   For each FMP descriptor, U-Boot:
-
-   Splits the firmware payload into 4 KiB chunks.
-   Invokes the PSA_FWU_Update API for each chunk, transmitting the buffer address via the FF-A (Firmware Framework for Arm) shared memory interface.
-
-#. **Secure Transmission and Forwarding**
-
-   The PSA Firmware Update (FWU) service, running as part of Trusted Services, receives the chunks through Secure Partition Client (SPC) calls.
-   It forwards these chunks to the Secure Enclave using MHU-based PSA calls.
-
-#. **Flashing Within the Secure Enclave**
-
-   Inside the Secure Enclave, the PSA FWU Agent dispatches each chunk to the shim layer.
-
-   The shim layer:
-
-   Erases the corresponding sectors in the non-active flash bank.
-   Writes the received firmware chunks at the correct offsets.
-   During partial updates, it also copies static partitions from the active bank to the non-active one to maintain consistency.
-
-#. **Finalization and Boot Preparation**
-
-   After all chunks are successfully written:
-
-   The shim updates the firmware manifest and the EFI System Resource Table (ESRT) entries to reflect the new image version.
-   This step enables the bootloader to recognize the new firmware for a trial boot.
-   The platform then performs an automatic reset, booting into the non-active bank in trial mode.
-
-#. **Trial Boot and Confirmation**
-
-   In trial mode, U-Boot evaluates the new firmware and issues either an accept or reject command using the PSA FWU ABI.
-   These commands are sent to the Secure Enclave, instructing the shim to update the firmware metadata accordingly.
-
-#. **Recovery and Fallback Mechanism**
-
-   If the trial boot is successful, the host sends an acknowledgment, transitioning the firmware state from 'trial' to 'regular'.
-
-   If the system fails or becomes unresponsive:
-
-   A watchdog timer triggers a system reset.
-   The BL1 firmware in the Secure Enclave detects repeated failures and reverts to the previously known-good flash bank.
-   This rollback mechanism ensures the device remains operational and recoverable, even after a failed update.
+Boot loaders in Secure Enclave and Host read the Metadata
+block to get the information on the boot bank. In the successful trial stage,
+the acknowledgment from the host moves the state of the system from trial to
+regular. Any failure in the trial stage or system hangs leads to a system
+reset. This is made sure by the use of watchdog hardware. The Secure Enclave's
+BL1 has the logic to identify multiple resets and eventually switch back to the
+previous good bank. The ability to revert to the previous bank is crucial to
+guarantee the availability of the device.

 UEFI Runtime Support in U-Boot
 ******************************

-The implementation of UEFI boot-time and runtime APIs requires persistent variable storage. In
-Corstone-1000, UEFI variables are stored using the Protected Storage (PS) service.
-
-The diagram below illustrates the data flow for storing UEFI variables. U-Boot’s UEFI subsystem
-communicates with the Secure World using the U-Boot FF-A driver, which interfaces with the `UEFI System Management Mode (SMM) service <trusted-services-uefi-smm-website_>`__.
-
-The SMM service provides support for the UEFI System Management Mode. This support is implemented by the SMM Gateway secure partition.
-The SMM service then uses the Proxy Protected Storage (PS) provided by the SE Proxy SP.
-These PS calls are forwarded to the Secure Enclave, following the communication path described earlier.

-Subject: [PATCH] plat: corstone1000: add Cortex-A320 support
-
-Introduce `CORSTONE1000_CORTEX_A320` to enable Cortex-A320 on
-Corstone-1000 while keeping Cortex-A35 as the default. When the
-define is enabled, the build switches from `cortex_a35.S` to
-`cortex_a320.S`, maintaining compatibility with existing A35-based
-designs.
-
-Also add Normal-World mappings for the Ethos-U85 NPU and its SRAM
-on Cortex-A320 platforms so U-Boot and other non-secure software
-can safely access these regions:
-
-* **Ethos-U85 registers**: base `0x1A050000`, size `0x00004000` (16 KB),
-  attrs `MT_DEVICE | MT_RW | MT_NS`
-* **Non-secure SRAM**: base `0x02400000`, size `0x00400000` (4 MB),
-  attrs `MT_MEMORY | MT_RW | MT_NS`
-
-Enable GICv3 with GIC-600 when building for Cortex-A320 (retain
-GICv2/GIC-400 for Cortex-A35):
-
-* Update `plat_my_core_pos()` and `plat_arm_calc_core_pos()` to use
-  the Cortex-A320 MPIDR_EL1 affinity layout.
-* Add an A320-specific core-position routine in assembly guarded by
-  `CORSTONE1000_CORTEX_A320`.
-* Switch to the GICv3 driver with GIC-600 extensions: update GIC base
-  addresses, use GICv3 APIs, and set `USE_GIC_DRIVER=3`,
-  `GICV3_SUPPORT_GIC600=1`, `GIC_ENABLE_V4_EXTN=1`.
-
-These changes prepare the platform for Cortex-A320 integration and
-ensure correct GIC configuration and secondary-core bring-up, while
-preserving A35 behavior.

-Subject: [PATCH] fix: exclude Boot requirement tests for Corstone-1000
-
-A test compares the value of the Generic Timer register CNTFRQ visible in
-two frames CNTBaseN and CNTCTLBase that are linked in Armv8-A and reflect
-the same value.
-    
-An issue in Corstone-1000 (errata 2142118) makes the CNTFRQ views
-inconsistents and the then test fails. There is no workaround and
-the test is skipped.

-Subject: [PATCH] plat: corstone1000: Add Cortex-A320 support
-
-Switch platform to GICv3 (GIC-600) for Corstone-1000 with Cortex-A320
-depending on CORSTONE1000_CORTEX_A320:
-    - Define GICD and GICR bases.
-    - Update the platform sources to include the GIC-V3 files.
-
-Move the NVM offset to prevent overlap with the TFTF firmware,
-which starts at 0x80000000 (TFTF_BASE).
-
-Introduce a new skip file tests_to_skip_cortex_a320 to be used when building
-TF-A-Tests with CORSTONE1000_CORTEX_A320=1. This ensures that tests which
-are not supported or cause traps on Corstone-1000 with Cortex-A320 are
-consistently skipped during execution.
-
-Skipped entries:
-    CPU extensions/AMUv1 suspend/resume
-    CPU extensions/Use trace buffer control Registers

+
+The BL1 writes the PLAT_NV_COUNTER_BL1_0 NV counter directly without

+function should not update the PLAT_NV_COUNTER_BL1_0 from the metadata.
+

+
+The UEFI variables are stored in the Protected Storage. The size of

+so the related buffer sizes have to be increased:
+
+- The PS_MAX_ASSET_SIZE needs to be big enough to store the variables.
+- The CRYPTO_ENGINE_BUF_SIZE needs to be increased because the encryption
+  of the bigger PS assets requires bigger buffer.
+- The CRYPTO_IOVEC_BUFFER_SIZE needs to be increased because the PS
+  assets are passed through the IOVEC buffer between the crypto and
+  PS partition during encryption.

- parameters for Corstone-1000
-
-The PS_NUM_ASSET is duplicated in the cmake.config and the
-config_tfm_target.h file under Corstone-1000. The commit removes
-the one from the cmake.config and keeps the one in the header file.
-
-The whole rationale behind this is for the vendor to be able
-to override the configuration using the cmake file.

+
+Previously, approximately only 2MB was used out of the 8MB SE Flash.
+The aim of this commit is to increase the size of PS storage in SE
+Flash.
+Increasing the size minimize the possibilities of it to run out
+of memory as it is not cleared on reset or reprogramming of the device.
+
+The FLASH_PS_AREA_SIZE is increased to 6MB so now 7MB of the SE Flash
+is used. The remaining 1MB is allocated for future uses.

-Subject: [PATCH 1/2] Platform: Corstone1000: Increase BL1 size and align
- binary addresses
-
-The move to Trusted-Firmware-M v2.2.1 makes the BL1 code larger,
-while the provisioning bundle can be trimmed.  At the same time BL2 and
-TF-M binary addresses now need to begin on a 0x100-byte boundary for
-Cortex-M0+ based platforms.
-
-Key changes
--------------------------------
- Increase `BL1_1_CODE_SIZE` to 58KB to accommodate the v2.2.1 binaries.
- Reduce `PROVISIONING_DATA_SIZE` to 6KB.
- `BL2_CODE_START` and `S_CODE_START` are aligned to 0x100 byte boundary
-   so both start addresses are an exact multiple of 0x100.

- restructure
-
-The BL2 build was restructured in order to always migrate to use
-MCUBOOT_USE_PSA_CRYPTO and then support hardware crypto drivers
-through the PSA driver interface instead of the _ALT interface
-which will be deprecated in newer versions of Mbed TLS. The ADAC
-enabled library will then use PSA Crypto APIs through the thin
-PSA Crypto core which is available in the BL2 build, without the
-need to link the old driver through psa_adac_cc312.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add support for powering on the Cortex-A320 host in the DSU-120T
-cluster and reserve Host SRAM for the normal world on the
-Corstone-1000 platform. These changes enable secure-enclave firmware
-control of the Cortex-A320 power domain and memory access

-
-**DSU-120T Power-Policy Unit (PPU) driver**
-
-* Introduce a minimal driver to program the DSU-120T Power-Policy
-  Units, allowing the secure-enclave firmware to bring the
-  Cortex-A320 host cluster out of reset.
-* The DSU utility-bus registers are located at:
-  * `0x6091_0000` in the Host memory map.
-  * `0xC091_0000` in the Secure-Enclave memory map.
-* The FC1 firewall is configured so that only the Secure Enclave may
-  write to this window.
-* Add new CMake option `CORSTONE1000_DSU_120T` and platform define to
-  enable Cortex-A320 DSU-120T–specific code.
-
-**Host SRAM allocation**
-
-* Reserve a 4 MiB block of Host SRAM at `0x0240_0000` for the
-  Cortex-A320 normal world.
-* Open the same region in the Host-side firewall (CVM, region 2)
-  to allow non-secure access.
-* This configuration is compiled in when `CORSTONE1000_CORTEX_A320`
-  is defined.
-
-These updates prepare the Corstone-1000 platform for Cortex-A320
-integration with proper cluster power management and normal-world
-memory accessibility.

+Subject: [PATCH 9/9] Platform: CS1000: Fix Bank offsets
+
+The BANK_0_PARTITION_OFFSET and BANK_1_PARTITION_OFFSET are used for
+erasing the banks during capsule update. The fwu_agent erases the flash
+using them as starting addresses. The BL2 (MCUBoot) should also

+Subject: [PATCH] Platform: CS1000: Increase BL2 partition size
+
+Enabling secure debug increases the BL2 code size considerably. This
+patch increases the BL2 partition size to enable secure debug feature
+on Corstone-1000. The TF-M partition size has to be decreased for this.
+The RAM_MPU_REGION_BLOCK_1_SIZE had to be aligned with the changes to
+fully cover the S_DATA.

+Subject: [PATCH 2/3] CC312: ADAC: Add PSA_WANT_ALG_SHA_256 definition
+
+The bl2_mbedcrypto_config is linked to the psa_adac_cc312 target so
+the MCUBOOT_PSA_CRYPTO_CONFIG_FILEPATH and
+MCUBOOT_MBEDCRYPTO_CONFIG_FILEPATH configs are used for the ADAC driver
+too. The MCUBOOT_USE_PSA_CRYPTO is OFF by default, that means the
+MCUBOOT_PSA_CRYPTO_CONFIG_FILEPATH is not included during the build so
+the PSA_WANT_ALG_SHA_256 is not defined for the ADAC driver. Because
+of this, the PSA_HASH_MAX_SIZE is not set correctly for the sources
+of the psa_adac_cc312 target. This caused runtime issues.

+
+The whole of the SRAM was configured unprivileged on this platform, so
+the memory protection required for isolation level 2 was not present.
+
+This patch changes the S_DATA_START to S_DATA_LIMIT MPU region to be
+configured for privileged access only. It also reorders the MPU regions
+so that the App RoT sub-region overlapping S_DATA has a higher region
+number and so takes priority in the operation of the Armv6-M MPU.

+Subject: [PATCH 3/5] Platform: CS1000: Fix compiler switch in BL1
+
+The fwu_agent.c used the "BL1" definition to check if the source file
+is building for the BL1 or for the TFM_S target.
+But the "BL1" definition is added to the build flags for every file
+that links against platform_region_defs, see
+tfm/cmake/spe-CMakeLists.cmake:
+
+target_compile_definitions(platform_region_defs
+    INTERFACE
+        $<$<BOOL:${BL1}>:BL1>
+       ....
+)
+
+This means the "#if BL1" condition was true for both cases.
+
+This commit:
+- Adds a new definition that is only added to the
+  platform_bl1_1 target.
+- Fixes the #elif with no expression error that came up.
+- Moves the partition table loading because previously it was not
+  loaded during the runtime TFM_S execution, only in BL2.

+Subject: [PATCH] Platform: CS1000: Validate both metadata replicas
+
+According to the [1] both metadata replica integrity should be checked
+during the update agent initialization, and if one of the replica is
+corrupted then it should be fixed by copying the other replica.
+
+This commit:
+- Adds the integrity check and correction to the
+  corstone1000_fwu_host_ack() function. This function is called when
+  the Host core has booted.
+- Updates the metadata_read() function so both replica can be read.
+- Adds metadata_write_replica() function to write metadata replicas
+  separately.

Hugues KAMBA MPIANA	4c490d2c2b	arm-bsp/documentation: corstone1000: Amend documentation for CORSTONE1000-2024.11 release * Fix typographical error in documentation. * Add missing instructions. * Create paragraphs where necessary to improve readability. * Change `note` box to `important` box * Remove verification of arm_tstee driver presence: arm-tstee driver has been integrated in Linux v6.10.14 which is the one used in the software stack. It is built as part of Linux and is no longer a loadable module. The steps to verify the driver presence are no longer applicable. * Standardise naming of the target platform: Consistently use the name `Corstone-1000` to refer to the target platform. * Update Debian OS version from 12.4 to 12.7 Debian version 12.4 has a bug in Shim 15.7. This bug causes a fatal error when attempting to boot media installer for Debian,and resets the platform before installation starts. A patch to skip the Shim was applied to Corstone-1000 to avoid the error. Debian version 12.7 no longer has the bug in the Shim thus making the usage of the patch redundant. Bump Debian installer to version 12.7 and remove usage of the patch for the Debian installation test. * Replace xterm with tmux: Update the user guide to specify tmux instead of xterm. Using tmux as opposed to xterm provides a better user experience when running the commands listed on the user guide. * Use ACS image for FVP SystemReady test: Due to fixed timeout values in the meta-arm-systemready the ACS time test do not complete successfully. Instead, specify commands to use the pre-built ACS image. * List Trusted Services as a host component: Add Trusted Services to the list of components used on the Host processor of the Corstone-1000. The various BitBake recipes and append files used to build Trusted Services are listed for the component. * Update release version to CORSTONE1000-2024.11: All references to the version of the Corstone-1000 software reference stack have been updated from CORSTONE1000-2024.06 to CORSTONE1000-2024.11.

Bence Balogh	d824ee371a	arm-bsp/trusted-firmware-m: corstone1000: Fix Secure Debug connection due to token version mismatch Due to a mismatch between the ADAC dummy token major version and the version in the secure-debug-manager repository [1]'s submodule [2], the secure debug connection was denied. Update the ADAC token major and minor versions in TF-M to align with the expected dummy token.

Jon Mason	acafe7c89f	CI: remove branch name The meta-arm styhead branch should be using the styhead branches of meta-clang, meta-virtualization, and meta-secure-core. Remove the master branch specific line to allow for these to be used. Signed-off-by: Jon Mason <jon.mason@arm.com>	2024-11-18 10:34:03 -05:00
Ziad Elhanafy	2a624d2239	arm-systemready/linux-distros: Follow WORKDIR -> UNPACKDIR transition This adapts to the oe-core rework to enforce a separate directory for unpacking local sources (UNPACKDIR) instead of polluting WORKDIR directly.

Jon Mason	ca9375b72d	CI: Rework qemuarm64-secureboot matrix qemuarm64-secureboot is using systemd for uefi-secureboot, which has warnings with musl (and fails to compile with clang and musl). So, modify the matrix to keep the coverage of everything else but musl. Signed-off-by: Jon Mason <jon.mason@arm.com>	2024-10-07 10:17:58 -04:00
Javier Tia	691d479ce4	arm/qemuarm64-secureboot: Enable UEFI Secure Boot Encapsulate all UEFI Secure Boot required settings in one Kas configuration file. Introduce SBSIGN_KEYS_DIR variable where UEFI keys will be generated to sign UEFI binaries. Introduce uefi-secureboot machine feature, which is being used to conditionally set the proper UEFI settings in recipes. Replace Grub bootloader with systemd-boot, which it makes easier to enable Secure Boot. Advantages using systemd as Init Manager: - Extending secure boot to userspace is a lot easier with systemd than with sysvinit where custom scripts will need to be written for all use cases. - systemd supports dm-verity and TPM devices for encryption usecases out of the box. Enabling them is a lot easier than writing custom scripts for sysvinit. - systemd also supports EUFI signing the UKI binaries which merge kernel, command line and initrd which helps in bringing secure boot towards rootfs. - systemd offers a modular structure with unit files that are more predictable and easier to manage than the complex and varied scripts used by SysVinit. This modularity allows for better control and customization of the boot process, which is beneficial in Secure Boot environments. - Add CI settings to build and test UEFI Secure Boot. Add one test to verify Secure Boot using OE Testing infraestructure: $ kas build ci/qemuarm64-secureboot.yml:ci/meta-secure-core.yml:ci/uefi-secureboot.yml:ci/testimage.yml ...

Javier Tia	67a28fc298	arm: Enable Secure Boot in all required recipes In the target, Secure Boot starts from the firmware (u-boot), adds the signing keys, and verifies the bootloader (systemd-boot) and kernel (Linux). sbsign bbclass is used to sign the binaries. sbsign is the name of the tool used to sign these binaries. Hence the name of this class to sbsign and variables with SBSIGN prefix. Signed-off-by: Javier Tia <javier.tia@linaro.org> Signed-off-by: Jon Mason <jon.mason@arm.com>	2024-10-07 10:17:44 -04:00
