This patch performs the following: - Creating two corstone700 platforms under corstone700 board: fvp and fpga - Since the FVP and FPGA have IP differences, this commit provides a specific DTS for each platform - The platform can be specified using the TARGET_PLATFORM Makefile variable (possible values are: fvp or fpga) - Allowing to use u-boot by: - Enabling NEED_BL33 option - Fixing non-secure image base: For no preloaded bl33 we want to have the NS base set on shared ram. Setup a memory map region for NS in shared map and set the bl33 address in the area. - Setting the SYS_COUNTER_FREQ_IN_TICKS based on the selected platform - Setting ARM_MAP_SHARED_RAM and ARM_MAP_NS_SHARED_RAM to use MT_MEMORY Change-Id: I4c8ac3387acb1693ab617bcccab00d80e340c163 Signed-off-by: Rui Miguel Silva <rui.silva@linaro.org> Signed-off-by: Abdellatif El Khlifi <abdellatif.elkhlifi@arm.com> |

Trusted Firmware-A
Trusted Firmware-A (TF-A) is a reference implementation of secure world software for Arm A-Profile architectures (Armv8-A and Armv7-A), including an Exception Level 3 (EL3) Secure Monitor. It provides a suitable starting point for productization of secure world boot and runtime firmware, in either the AArch32 or AArch64 execution states.
TF-A implements Arm interface standards, including:
- 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)
The code is designed to be portable and reusable across hardware platforms and software models that are based on the Armv8-A and Armv7-A architectures.
In collaboration with interested parties, we will continue to enhance TF-A with reference implementations of Arm standards to benefit developers working with Armv7-A and Armv8-A TrustZone technology.
Users are encouraged to do their own security validation, including penetration testing, on any secure world code derived from TF-A.
