Hi Weizhao,
- if (request_psci_features(ARM_SMCCC_ARCH_FEATURES) ==
if (request_psci_features(ARM_SMCCC_VERSION) == PSCI_RET_NOT_SUPPORTED) return 0;
if (invoke_psci_fn(ARM_SMCCC_VERSION, 0, 0, 0) < ARM_SMCCC_VERSION_1_1)
return 0;
It makes sense to me, thanks.

Apart from ARM_SMCCC_VERSION_1_1, are the other ARM_SMCCC_VERSION_1_x defines needed ?
