Indices and tables
==================
Trusted Firmware-A (TF-A) provides a reference implementation of secure world
software for `Armv7-A and Armv8-A`_, including a `Secure Monitor`_ executing
at Exception Level 3 (EL3). It implements various Arm interface standards,
such as:
* :ref:`genindex`
* :ref:`modindex`
* :ref:`search`
- The `Power State Coordination Interface (PSCI)`_
- `Trusted Board Boot Requirements CLIENT (TBBR-CLIENT)`_
- `SMC Calling Convention`_
- `System Control and Management Interface (SCMI)`_
- `Software Delegated Exception Interface (SDEI)`_
Where possible, the code is designed for reuse or porting to other Armv7-A and
Armv8-A model and hardware platforms.
This release provides a suitable starting point for productization of secure
world boot and runtime firmware, in either the AArch32 or AArch64 execution
states.
Users are encouraged to do their own security validation, including penetration
testing, on any secure world code derived from TF-A.
Arm will continue development in collaboration with interested parties to
provide a full reference implementation of Secure Monitor code and Arm standards
to the benefit of all 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 ``ENABLE_PAUTH``
build flag to be set.
- 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 the `Firmware Design`_ and supporting documentation. The `Change Log`_
provides details of changes made since the last release.
