+Feature Overview
+================
+
+This page provides an overview of the current |TF-A| feature set. For a full
+description of these features and their implementation details, please see
+the documents that are part of the *Components* and *System Design* chapters.
+
+The :ref:`Change Log & Release Notes` provides details of changes made since the
+last release.
+
+Current features
+----------------
+
+-  Initialization of the secure world, for example exception vectors, control
+   registers and interrupts for the platform.
+
+-  Library support for CPU specific reset and power down sequences. This
+   includes support for errata workarounds and the latest Arm DynamIQ CPUs.
+
+-  Drivers to enable standard initialization of Arm System IP, for example
+   Generic Interrupt Controller (GIC), Cache Coherent Interconnect (CCI),
+   Cache Coherent Network (CCN), Network Interconnect (NIC) and TrustZone
+   Controller (TZC).
+
+-  A generic |SCMI| driver to interface with conforming power controllers, for
+   example the Arm System Control Processor (SCP).
+
+-  SMC (Secure Monitor Call) handling, conforming to the `SMC Calling
+   Convention`_ using an EL3 runtime services framework.
+
+-  |PSCI| library support for CPU, cluster and system power management
+   use-cases.
+   This library is pre-integrated with the AArch64 EL3 Runtime Software, and
+   is also suitable for integration with other AArch32 EL3 Runtime Software,
+   for example an AArch32 Secure OS.
+
+-  A minimal AArch32 Secure Payload (*SP_MIN*) to demonstrate |PSCI| library
+   integration with AArch32 EL3 Runtime Software.
+
+-  Secure Monitor library code such as world switching, EL1 context management
+   and interrupt routing.
+   When a Secure-EL1 Payload (SP) is present, for example a Secure OS, the
+   AArch64 EL3 Runtime Software must be integrated with a Secure Payload
+   Dispatcher (SPD) component to customize the interaction with the SP.
+
+-  A Test SP and SPD to demonstrate AArch64 Secure Monitor functionality and SP
+   interaction with PSCI.
+
+-  SPDs for the `OP-TEE Secure OS`_, `NVIDIA Trusted Little Kernel`_
+   and `Trusty Secure OS`_.
+
+-  A Trusted Board Boot implementation, conforming to all mandatory TBBR
+   requirements. This includes image authentication, Firmware Update (or
+   recovery mode), and packaging of the various firmware images into a
+   Firmware Image Package (FIP).
+
+-  Pre-integration of TBB with the Arm CryptoCell product, to take advantage of
+   its hardware Root of Trust and crypto acceleration services.
+
+-  Reliability, Availability, and Serviceability (RAS) functionality, including
+
+   -  A Secure Partition Manager (SPM) to manage Secure Partitions in
+      Secure-EL0, which can be used to implement simple management and
+      security services.
+
+   -  An |SDEI| dispatcher to route interrupt-based |SDEI| events.
+
+   -  An Exception Handling Framework (EHF) that allows dispatching of EL3
+      interrupts to their registered handlers, to facilitate firmware-first
+      error handling.
+
+-  A dynamic configuration framework that enables each of the firmware images
+   to be configured at runtime if required by the platform. It also enables
+   loading of a hardware configuration (for example, a kernel device tree)
+   as part of the FIP, to be passed through the firmware stages.
+
+-  Support for alternative boot flows, for example to support platforms where
+   the EL3 Runtime Software is loaded using other firmware or a separate
+   secure system processor, or where a non-TF-A ROM expects BL2 to be loaded
+   at EL3.
+
+-  Support for the GCC, LLVM and Arm Compiler 6 toolchains.
+
+-  Support for combining several libraries into a "romlib" image that may be
+   shared across images to reduce memory footprint. The romlib image is stored
+   in ROM but is accessed through a jump-table that may be stored
+   in read-write memory, allowing for the library code to be patched.
+
+-  A prototype implementation of a Secure Partition Manager (SPM) that is based
+   on the SPCI Alpha 1 and SPRT draft specifications.
+
+-  Support for ARMv8.3 pointer authentication in the normal and secure worlds.
+   The use of pointer authentication in the normal world is enabled whenever
+   architectural support is available, without the need for additional build
+   flags. Use of pointer authentication in the secure world remains an
+   experimental configuration at this time and requires the
+   ``BRANCH_PROTECTION`` option to be set to non-zero.
+
+-  Position-Independent Executable (PIE) support. Initially for BL31 only, with
+   further support to be added in a future release.
+
+Still to come
+-------------
+
+-  Support for additional platforms.
+
+-  Refinements to Position Independent Executable (PIE) support.
+
+-  Continued support for the draft SPCI specification, to enable the use of
+   secure partition management in the secure world.
+
+-  Documentation enhancements.
+
+-  Ongoing support for new architectural features, CPUs and System IP.
+
+-  Ongoing support for new Arm system architecture specifications.
+
+-  Ongoing security hardening, optimization and quality improvements.

+Release Processes
+=================
+
+Project Release Cadence
+-----------------------
+
+The project currently aims to do a release once every 6 months which will be
+tagged on the master branch. There will be a code freeze (stop merging
+non-essential changes) up to 4 weeks prior to the target release date. The release
+candidates will start appearing after this and only bug fixes or updates
+required for the release will be merged. The maintainers are free to use their
+judgement on what changes are essential for the release. A release branch may be
+created after code freeze if there are significant changes that need merging onto
+the integration branch during the merge window.
+
+The release testing will be performed on release candidates and depending on
+issues found, additional release candidates may be created to fix the issues.

+
+   - ti/k3: common: Fix RO data area size calculation
+
+- Security
+   - AArch32: Disable Secure Cycle Counter
+      - Changes the implementation for disabling Secure Cycle Counter.
+        For ARMv8.5 the counter gets disabled by setting ``SDCR.SCCD`` bit on
+        CPU cold/warm boot. For the earlier architectures PMCR register is
+        saved/restored on secure world entry/exit from/to Non-secure state,
+        and cycle counting gets disabled by setting PMCR.DP bit.
+   - AArch64: Disable Secure Cycle Counter
+      - For ARMv8.5 the counter gets disabled by setting ``MDCR_El3.SCCD`` bit on

 with reference implementations of Arm standards to benefit developers working
 with Armv7-A and Armv8-A TrustZone technology.
 
-Functionality
--------------
-
--  Initialization of the secure world, for example exception vectors, control
-   registers and interrupts for the platform.
-
--  Library support for CPU specific reset and power down sequences. This
-   includes support for errata workarounds and the latest Arm DynamIQ CPUs.
-
--  Drivers to enable standard initialization of Arm System IP, for example
-   Generic Interrupt Controller (GIC), Cache Coherent Interconnect (CCI),
-   Cache Coherent Network (CCN), Network Interconnect (NIC) and TrustZone
-   Controller (TZC).
-
--  A generic `SCMI`_ driver to interface with conforming power controllers, for
-   example the Arm System Control Processor (SCP).
-
--  SMC (Secure Monitor Call) handling, conforming to the `SMC Calling
-   Convention`_ using an EL3 runtime services framework.
-
--  `PSCI`_ library support for CPU, cluster and system power management
-   use-cases.
-   This library is pre-integrated with the AArch64 EL3 Runtime Software, and
-   is also suitable for integration with other AArch32 EL3 Runtime Software,
-   for example an AArch32 Secure OS.
-
--  A minimal AArch32 Secure Payload (SP\_MIN) to demonstrate `PSCI`_ library
-   integration with AArch32 EL3 Runtime Software.
-
--  Secure Monitor library code such as world switching, EL1 context management
-   and interrupt routing.
-   When a Secure-EL1 Payload (SP) is present, for example a Secure OS, the
-   AArch64 EL3 Runtime Software must be integrated with a Secure Payload
-   Dispatcher (SPD) component to customize the interaction with the SP.
-
--  A Test SP and SPD to demonstrate AArch64 Secure Monitor functionality and SP
-   interaction with PSCI.
-
--  SPDs for the `OP-TEE Secure OS`_, `NVIDIA Trusted Little Kernel`_
-   and `Trusty Secure OS`_.
-
--  A Trusted Board Boot implementation, conforming to all mandatory TBBR
-   requirements. This includes image authentication, Firmware Update (or
-   recovery mode), and packaging of the various firmware images into a
-   Firmware Image Package (FIP).
-
--  Pre-integration of TBB with the Arm CryptoCell product, to take advantage of
-   its hardware Root of Trust and crypto acceleration services.
-
--  Reliability, Availability, and Serviceability (RAS) functionality, including
-
-   -  A Secure Partition Manager (SPM) to manage Secure Partitions in
-      Secure-EL0, which can be used to implement simple management and
-      security services.
-
-   -  An |SDEI| dispatcher to route interrupt-based |SDEI| events.
-
-   -  An Exception Handling Framework (EHF) that allows dispatching of EL3
-      interrupts to their registered handlers, to facilitate firmware-first
-      error handling.
-
--  A dynamic configuration framework that enables each of the firmware images
-   to be configured at runtime if required by the platform. It also enables
-   loading of a hardware configuration (for example, a kernel device tree)
-   as part of the FIP, to be passed through the firmware stages.
-
--  Support for alternative boot flows, for example to support platforms where
-   the EL3 Runtime Software is loaded using other firmware or a separate
-   secure system processor, or where a non-TF-A ROM expects BL2 to be loaded
-   at EL3.
-
--  Support for the GCC, LLVM and Arm Compiler 6 toolchains.
-
--  Support for combining several libraries into a "romlib" image that may be
-   shared across images to reduce memory footprint. The romlib image is stored
-   in ROM but is accessed through a jump-table that may be stored
-   in read-write memory, allowing for the library code to be patched.
-
--  A prototype implementation of a Secure Partition Manager (SPM) that is based
-   on the SPCI Alpha 1 and SPRT draft specifications.
-
--  Support for ARMv8.3 pointer authentication in the normal and secure worlds.
-   The use of pointer authentication in the normal world is enabled whenever
-   architectural support is available, without the need for additional build
-   flags. Use of pointer authentication in the secure world remains an
-   experimental configuration at this time and requires the
-   ``BRANCH_PROTECTION`` option to be set to non-zero.
-
--  Position-Independent Executable (PIE) support. Initially for BL31 only, with
-   further support to be added in a future release.
-
-For a full description of functionality and implementation details, please
-see :ref:`Firmware Design` and supporting documentation. The
-:ref:`Change Log & Release Notes` provides details of changes made since the
-last release.

-Release Processes
-=================
-
-Project Release Cadence
------------------------
-
-The project currently aims to do a release once every 6 months which will be
-tagged on the master branch. There will be a code freeze (stop merging
-non-essential PRs) up to 4 weeks prior to the target release date. The release
-candidates will start appearing after this and only bug fixes or updates
-required for the release will be merged. The maintainers are free to use their
-judgement on what PRs are essential for the release. A release branch may be
-created after code freeze if there are significant PRs that need merging onto
-the integration branch during the merge window.
-
-The release testing will be performed on release candidates and depending on
-issues found, additional release candidates may be created to fix the issues.
