TBB: add support to include certificates in a FIP image This patch extends the FIP tool to include the certificates generated by the 'cert_create' tool. If GENERATE_COT build option is enabled, the Makefile adds the certificates as dependencies to create the FIP file. Thus, make target 'fip' will also build the certificates as part of the Trusted Firmware build process. Change-Id: I5eee500da7f7be6cfb6e3df0423599739d260074
ARM Trusted Firmware provides a reference implementation of secure world software for ARMv8-A, including Exception Level 3 (EL3) software. This release provides initial support for the [Juno ARM Development Platform] Juno, complementing the existing support for the Base and Foundation [Fixed Virtual Platforms (FVPs)] FVP from ARM.
The intent is to provide a reference implementation of various ARM interface standards, such as the Power State Coordination Interface (PSCI), Trusted Board Boot Requirements (TBBR) and [Secure Monitor] TEE-SMC code. As far as possible the code is designed for reuse or porting to other ARMv8-A model and hardware platforms.
ARM will continue development in collaboration with interested parties to provide a full reference implementation of PSCI, TBBR and Secure Monitor code to the benefit of all developers working with ARMv8-A TrustZone technology.
The software is provided under a BSD 3-Clause license. Certain source files are derived from FreeBSD code: the original license is included in these source files.
This release is a limited functionality implementation of the Trusted Firmware. It provides a suitable starting point for productization. Future versions will contain new features, optimizations and quality improvements.
Initial implementation of a subset of the Trusted Board Boot Requirements Platform Design Document (PDD). This includes packaging the various firmware images into a Firmware Image Package (FIP) to be loaded from non-volatile storage.
Initializes the secure world (for example, exception vectors, control registers, GIC and interrupts for the platform), before transitioning into the normal world.
Supports both GICv2 and GICv3 initialization for use by normal world software.
Starts the normal world at the Exception Level and Register Width provided by the platform port. Typically this is AArch64 EL2 if available.
Handles SMCs (Secure Monitor Calls) conforming to the [SMC Calling Convention PDD] SMCCC using an EL3 runtime services framework.
Handles SMCs relating to the [Power State Coordination Interface PDD] PSCI for the Secondary CPU Boot, CPU Hotplug, CPU Idle and System Shutdown/Reset use-cases.
A Test Secure-EL1 Payload and Dispatcher to demonstrate Secure Monitor functionality such as world switching, EL1 context management and interrupt routing. This also demonstrates Secure-EL1 interaction with PSCI. Some of this functionality is provided in library form for re-use by other Secure-EL1 Payload Dispatchers.
Support for alternative Trusted Boot Firmware. Some platforms have their own Trusted Boot implementation and only require the Secure Monitor functionality provided by ARM Trusted Firmware.
Isolation of memory accessible by the secure world from the normal world through programming of a TrustZone controller.
Support for CPU specific reset sequences, power down sequences and register dumping during crash reporting. The CPU specific reset sequences include support for errata workarounds.
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.
This release of the Trusted Firmware has been tested on Revision B of the [Juno ARM Development Platform] Juno with Version r0p0-00rel7 of the [ARM SCP Firmware] SCP download.
The Trusted Firmware has also been tested on the 64-bit Linux versions of the following ARM FVPs:
Foundation_v8 (Version 2.1, Build 9.0.24)FVP_Base_AEMv8A-AEMv8A (Version 5.8, Build 0.8.5802)FVP_Base_Cortex-A57x4-A53x4 (Version 5.8, Build 0.8.5802)FVP_Base_Cortex-A57x1-A53x1 (Version 5.8, Build 0.8.5802)FVP_Base_Cortex-A57x2-A53x4 (Version 5.8, Build 0.8.5802)The Foundation FVP can be downloaded free of charge. The Base FVPs can be licensed from ARM: see [www.arm.com/fvp] FVP.
Complete Trusted Boot implementation.
Complete implementation of the PSCI specification.
Support for alternative types of Secure-EL1 Payloads.
Completing the currently experimental GICv3 support.
Support for new System IP devices.
