[TF-A] Glitching protection

Hi

Trusted Firmware M recently introduced protection against glitching at key decision points: https://github.com/mcu-tools/mcuboot/pull/776

To me this is a key mitigation element for companies that target PSA level 3 compliance which means hardware attacks resilience.

I believe similar techniques need to be used in different projects involved in Linux secure booting (TF-A, OP-TEE, U-Boot, Linux kernel).

Are there any efforts planned around this ?

Is it feasible to have a "library" that could be integrated in different projects?

Cheers
