Is it possible to inform the FPGA side of WFI/WFE State, a Coretex-A9 feature, with Cyclone® V SoC?

It is possible to propagate each output by enabling Enable MPU Standby and event signals in the HPS IP configuration.

h2f_mpu_standbywfe[1:0] 
h2f_mpu_standbywfi[1:0]

The state of each core is propagated respectively.
