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>;
+ };
+ };
