This series adds a Linux TEE driver for MbedTEE, a Trusted Execution Environment for embedded systems (https://github.com/mbedtee). Two RPC transports are provided for systems where platform firmware or board configuration has already established the REE/TEE separation before Linux boots: - ARM/ARM64: SMC calls and GIC SPI notifications (TrustZone) - RISC-V: shared-memory ring buffers and IMSIC MSI notifications The driver implements the TEE subsystem interface (tee_driver_ops) and provides GlobalPlatform TEE Client API support, dynamic shared memory registration, and tee-supplicant support for REE filesystem and RPMB operations. The series is structured as follows: [1/3] dt-bindings: vendor-prefixes: add mbedtee [2/3] dt-bindings: firmware: add mbedtee,rpc binding [3/3] tee: add MbedTEE driver Xing Loong (3): dt-bindings: vendor-prefixes: add mbedtee dt-bindings: firmware: add mbedtee,rpc binding tee: add MbedTEE driver .../bindings/firmware/mbedtee,rpc.yaml | 221 +++++++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + Documentation/tee/index.rst | 1 + Documentation/tee/mbedtee.rst | 155 +++++ MAINTAINERS | 9 + drivers/tee/Kconfig | 3 +- drivers/tee/Makefile | 1 + drivers/tee/mbedtee/Kconfig | 20 + drivers/tee/mbedtee/Makefile | 11 + drivers/tee/mbedtee/core.c | 236 +++++++ drivers/tee/mbedtee/mbedtee_drv.h | 269 ++++++++ drivers/tee/mbedtee/mbedtee_msg.h | 219 +++++++ drivers/tee/mbedtee/rpc_callee.c | 609 ++++++++++++++++++ drivers/tee/mbedtee/rpc_callee_arm.c | 91 +++ drivers/tee/mbedtee/rpc_callee_riscv.c | 203 ++++++ drivers/tee/mbedtee/rpc_caller.c | 539 ++++++++++++++++ drivers/tee/mbedtee/rpc_caller_arm.c | 66 ++ drivers/tee/mbedtee/rpc_caller_riscv.c | 192 ++++++ drivers/tee/mbedtee/shm_pool.c | 105 +++ drivers/tee/mbedtee/shm_pool.h | 15 + drivers/tee/mbedtee/supp.c | 310 +++++++++ include/uapi/linux/tee.h | 1 + 22 files changed, 3277 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/firmware/mbedtee,rpc.yaml create mode 100644 Documentation/tee/mbedtee.rst create mode 100644 drivers/tee/mbedtee/Kconfig create mode 100644 drivers/tee/mbedtee/Makefile create mode 100644 drivers/tee/mbedtee/core.c create mode 100644 drivers/tee/mbedtee/mbedtee_drv.h create mode 100644 drivers/tee/mbedtee/mbedtee_msg.h create mode 100644 drivers/tee/mbedtee/rpc_callee.c create mode 100644 drivers/tee/mbedtee/rpc_callee_arm.c create mode 100644 drivers/tee/mbedtee/rpc_callee_riscv.c create mode 100644 drivers/tee/mbedtee/rpc_caller.c create mode 100644 drivers/tee/mbedtee/rpc_caller_arm.c create mode 100644 drivers/tee/mbedtee/rpc_caller_riscv.c create mode 100644 drivers/tee/mbedtee/shm_pool.c create mode 100644 drivers/tee/mbedtee/shm_pool.h create mode 100644 drivers/tee/mbedtee/supp.c base-commit: 03e2778d1f11de9260543f969e9e888a1c2bf830 -- 2.43.0
