abca35a69f9bea0496cf05e025c3c36e6d5ea68b - ta: pas: Add Qualcomm PAS TA

Tue, 31 Mar 2026 09:21:54 +0000

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 Reviewed-by: Sumit Garg List of files: /optee_os/core/pta/qcom/pas/pta_qcom_pas.c

f2eec4a00c32ef5ee20105318bc18f3eb52116c7 - pta: qcom: pas: map PAS resources on demand

Tue, 31 Mar 2026 09:20:09 +0000

pta: qcom: pas: map PAS resources on demandStop registering PAS-related IO regions at platform initializationtime and instead map them on demand when the PAS PTA is initialized.The WPSS, TURING, LPASS and IRIS regions were previously mappedstatically via register_phys_mem(). These mappings are now removedand the PAS controller region is mapped dynamically usingcore_mmu_add_mapping() when the PTA performs the memory setup.Since PAS resources are now mapped late, increaseCFG_RESERVED_VASPACE_SIZE to ensure sufficient virtual addressspace is available.This change reduces permanent IO mappings and keeps PAS resourceslocalized to the PTA implementation.Signed-off-by: Jorge Ramirez-Ortiz Reviewed-by: Sumit Garg List of files: /optee_os/core/pta/qcom/pas/pta_qcom_pas.c
