Changes in qcom_pas en Copyright 2025 Java abca35a69f9bea0496cf05e025c3c36e6d5ea68b - ta: pas: Add Qualcomm PAS TA http://opengrok.muzhidianzi.cn:8080/history/optee_os/ta/qcom_pas/#abca35a69f9bea0496cf05e025c3c36e6d5ea68b ta: pas: Add Qualcomm PAS TACertificate chain validation requires substantial parsing, which is notsuitable for the constrained S-EL1 environment. While signatureverification is supported by the crypto API, extending the TEE core/PTAto handle full chain parsing would increase complexity and TCB size.Move certificate validation to a user TA, keeping the PTA for platformoperations (PAS control, firmware loading, resets). This allows reuse ofexisting parsing libraries and keeps the core minimal.Signed-off-by: Jorge Ramirez-Ortiz <jorge.ramirez@oss.qualcomm.com>Reviewed-by: Sumit Garg <sumit.garg@oss.qualcomm.com> List of files: /optee_os/ta/qcom_pas/Makefile/optee_os/ta/qcom_pas/include/ta_qcom_pas.h/optee_os/ta/qcom_pas/src/qcom_pas.c/optee_os/ta/qcom_pas/src/sub.mk/optee_os/ta/qcom_pas/src/user_ta_header_defines.h/optee_os/ta/qcom_pas/sub.mk/optee_os/ta/qcom_pas/user_ta.mk Tue, 31 Mar 2026 09:00:00 +0000 Jorge Ramirez-Ortiz <jorge.ramirez@oss.qualcomm.com>
