The .rela.dyn section is the same for BL2-AT-EL3, BL31, TSP. Move it to the common header file. I slightly changed the definition so that we can do "RELA_SECTION >RAM". It still produced equivalent elf images. Please note I got rid of '.' from the VMA field. Otherwise, if the end of previous .data section is not 8-byte aligned, it fails to link. aarch64-linux-gnu-ld.bfd: warning: changing start of section .rela.dyn by 4 bytes aarch64-linux-gnu-ld.bfd: warning: changing start of section .rela.dyn by 4 bytes aarch64-linux-gnu-ld.bfd: warning: changing start of section .rela.dyn by 4 bytes make: *** [Makefile:1071: build/qemu/release/bl31/bl31.elf] Error 1 Change-Id: Iba7422d99c0374d4d9e97e6fd47bae129dba5cc9 Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.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.
