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
