When the board was added, enabling tzc380 was left off by mistake. The optee was tested with the following configuration in s2pro

+ firmware { + optee { + compatible = "linaro,optee-tz"; + method = "smc"; + }; + }; + + reserved-memory { + #address-cells = <2>; + #size-cells = <2>; + ranges; + + /* 6MiB */ + optee_core@5f800000 { + reg = <0x00 0x5f800000 0x00 0x600000>; + }; + + /* 2MiB */ + optee_shm@5fe00000 { + reg = <0x00 0x5fe00000 0x00 0x200000>; + }; + }; +
