SCP-firmware Change Log
=======================
Copyright (c) 2019, Arm Limited and Contributors. All rights reserved.
SCP-firmware - version 2.4.0
============================
New features
------------
- Module-based architecture with an event-driven execution model:
- Firmware code is organized into modules, where a module fulfills a well-
defined role (driver HAL, driver, protocol or service).
- A framework drives the initialization, orchestration of, and interactions
between modules.
- Processor-agnostic module code enables firmware portability across systems:
- Processor-dependent features (e.g. interrupt handling) are abstracted from
the modules by the framework.
- The framework relies on an interface whose implementation is processor-
dependent to provide these features.
- Module configurability easing the re-use of modules on different platforms:
- Strict split between the hardware and software feature configuration data
and module code.
- A native framework test suite provides rapid development and validation of the
core framework implementation.
- Support for Armv7-M control processor architecture based on CMSIS v5 and Keil
RTX 5.
- Provides system initialization support to enable boot of the application
cores.
- Provides the following runtime services:
- Power domain management
- System power management
- Performance domain management (Dynamic voltage and frequency scaling)
- Clock management
- Sensor management
- Provides a reference implementation of the System Control and Management
Interface v1.0 (SCMI, platform-side). The SCMI specification can be found
[here](http://infocenter.arm.com/help/topic/com.arm.doc.den0056a/DEN0056A_System_Control_and_Management_Interface.pdf).
- Provides a build system supporting:
- The GNU Arm Embedded and Arm Compiler 6 toolchains
- Platforms with multiple firmware images
- In-source Doxygen documentation
- Support for the SGM-775 platform
Known issues
------------
- The build system does not configure the compiler to avoid code generation of
unaligned accesses. As ARMv7-M targets are configured to trap on unaligned
word or halfword accesses, this can result in hardware exceptions.
[This patch](https://github.com/ARM-software/SCP-firmware/commit/d2a77e0d4d0d369f7504c032a380578a4d145438)
fixes this issue.
