cert_create: update help message

The help message printed by the cert_create tool using the command
line option -h (or --help) does not correctly list all the available
command line options.

This patch reworks the print_help() function to print the help
messages in a data driven approach. For each command line option
registered, an optional help message can be specified, which will
be printed by print_help().

Help messages for the TBBR options (certificates, keys and images)
are also provided.

Fix a small bug in the short options string passed to getopt_long:
the ':' was missing in the '-a' option (this option must take an
argument).

Fixes ARM-software/tf-issues#337

ARM Trusted Firmware - version 1.2

ARM Trusted Firmware provides a reference implementation of secure world software for ARMv8-A, including a [Secure Monitor] TEE-SMC executing at Exception Level 3 (EL3). It implements various ARM interface standards, such as the Power State Coordination Interface (PSCI), Trusted Board Boot Requirements (TBBR, ARM DEN0006C-1) and SMC Calling Convention. 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.

License

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

This release provides a suitable starting point for productization of secure world boot and runtime firmware. Future versions will contain new features, optimizations and quality improvements.

Users are encouraged to do their own security validation, including penetration testing, on any secure world code derived from ARM Trusted Firmware.

Functionality

  • Initialization of the secure world (for example, exception vectors, control registers, interrupt controller and interrupts for the platform), before transitioning into the normal world at the Exception Level and Register Width specified by the platform.

  • Library support for CPU specific reset and power down sequences. This includes support for errata workarounds.

  • Drivers for both the version 2.0 and version 3.0 ARM Generic Interrupt Controller specifications (GICv2 and GICv3). The latter also enables GICv3 hardware systems that do not contain legacy GICv2 support.

  • Drivers to enable standard initialization of ARM System IP, for example Cache Coherent Interconnect (CCI), Cache Coherent Network (CCN), Network Interconnect (NIC) and TrustZone Controller (TZC).

  • SMC (Secure Monitor Call) handling, conforming to the SMC Calling Convention using an EL3 runtime services framework.

  • SMC handling relating to PSCI for the Secondary CPU Boot, CPU Hotplug, CPU Idle and System Shutdown/Reset/Suspend use-cases.

  • Secure Monitor library code such as world switching, EL1 context management and interrupt routing. This must be integrated with a Secure-EL1 Payload Dispatcher (SPD) component to customize the interaction with a Secure-EL1 Payload (SP), for example a Secure OS.

  • A Test Secure-EL1 Payload and Dispatcher to demonstrate Secure Monitor functionality and Secure-EL1 interaction with PSCI.

  • SPDs for the OP-TEE Secure OS and [NVidia Trusted Little Kernel] NVidia TLK.

  • A Trusted Board Boot implementation, conforming to all mandatory TBBR requirements. This includes image authentication using certificates, a Firmware Update (or recovery mode) boot flow, and packaging of the various firmware images into a Firmware Image Package (FIP) to be loaded from non-volatile storage.

  • Support for alternative boot flows. Some platforms have their own boot firmware and only require the ARM Trusted Firmware Secure Monitor functionality. Other platforms require minimal initialization before booting into an arbitrary EL3 payload.

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.

Platforms

This release of the Trusted Firmware has been tested on variants r0 and r1 of the [Juno ARM Development Platform] Juno with [Linaro Release 15.10] Linaro Release Notes.

The Trusted Firmware has also been tested on the 64-bit Linux versions of the following ARM FVPs:

  • Foundation_Platform (Version 9.4, Build 9.4.59)
  • FVP_Base_AEMv8A-AEMv8A (Version 7.0, Build 0.8.7004)
  • FVP_Base_Cortex-A57x4-A53x4 (Version 7.0, Build 0.8.7004)
  • FVP_Base_Cortex-A57x1-A53x1 (Version 7.0, Build 0.8.7004)
  • FVP_Base_Cortex-A57x2-A53x4 (Version 7.0, Build 0.8.7004)

The Foundation FVP can be downloaded free of charge. The Base FVPs can be licensed from ARM: see [www.arm.com/fvp] FVP.

This release also contains the following platform support:

  • NVidia T210 and T132 SoCs
  • MediaTek MT8173 SoC

Still to Come

  • Complete implementation of the PSCI v1.0 specification.

  • Support for new CPUs and System IP.

  • More platform support.

  • Optimization and quality improvements.

For a full list of detailed issues in the current code, please see the Change Log and the GitHub issue tracker.
