NXP specifc macro SET_NXP_MAKE_FLAG is added. NXP has pool of multiple IPs. This macro helps: - In soc.mk, this macro help the selected IP source files to be included for that SoC. -- The set of IPs required for one NXP SoC is different to the set of IPs required by another NXP SoC. - For the same SoC, -- For one feature, the IP may be required in both BL2 and BL31. -- Without the above feature, that IP may be required in one. This macro help in selecting the inclusion of source and header files to: --- BL2 only --- BL31 only --- COMM (used by BL2 and BL31) Signed-off-by: Pankaj Gupta <pankaj.gupta@nxp.com> Change-Id: I2cdb13b89aa815fc5219cf8bfb9666d0a9f78765 |

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.
