plat/marvell: comphy: Add support for SFI on Lane 4
Konstantin Porotchkin authored 
Add static configuration for SFI+ 10Gbps interface on SERDES
Lane 4.
This is just a copy of Lane 2 static values, not optimized.
Board-to-board iperf test shows up to 6Gbps transfer speed.

Trusted Firmware-A - version 2.0

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:

Where possible, the code is designed for reuse or porting to other Armv7-A and Armv8-A model and hardware platforms.

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.

This release

This release provides a suitable starting point for productization of secure world boot and runtime firmware, in either the AArch32 or AArch64 execution state.

Users are encouraged to do their own security validation, including penetration testing, on any secure world code derived from TF-A.

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 dispatcher component (SPD) to customize the interaction with the SP.
  • A Test SP/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 combining several libraries into a self-called "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.

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.
