[TF-A] Re: MISRA-C violation for unused functions in Trusted Firmware-A(TFA) code

Hello,

Generally speaking, I think we should keep TF-A codebase free of dead code. Dead code can lead to confusion for developers and also can potentially be used as gadgets to exploit some security vulnerability.

Could you please provide a list of such unused functions?

Please bare in mind that some functions will only be used on some platforms or when a specific feature is enabled through a compile-time flag. So these would not be considered as dead code as such.

Best regards, Sandrine
