In my opinion, the "QCOM_Q6V5_PAS" based Peripheral Authentication platforms may have the register information completely removed. There are two types of Peripheral Authentication supported: "QCOM_Q6V5_MSS" (self-authenticating) "QCOM_Q6V5_PAS" (trust-zone based Authentication) For "QCOM_Q6V5_PAS" based Peripheral Authentication platforms, use SCM calls instead of the register-based mechanism. So it is no need to expose the PUB reg addresses for those platforms. -- Thx and BRs, Aiqun(Maria) Yu
