>RISC-V Trusted Executable Environment security software includes linux,
opensbi, and OP-TEE OS. linux is the non-secure domain, and OP-TEE OS is the
secure domain. At boot time, opensbi boots OP->TEE OS and then starts linux.
At runtime, opensbi acts as a secure monitor, responsible for context saving
and restoring when switching between linux and OP-TEE OS.
>TEE function is off by default, when using configuration is added in the
config and objects file, such as platform/generic/configs/defconfig add
CONFIG_SBI_ECALL_TEE = y, In the >platform/generic/objects.mk add
CONFIG_TEE_LOAD_ADDR = 0x27c000000, CONFIG_TEE_LOAD_ADDR is the starting
address of the OP-TEE OS.

Hi Liushiwei,

Was there any formal specification or draft for this? Could you please point
me to the draft or specification?

Regards
Himanshu
