Hi, system shutdown or system reset PSCI calls are invoked by the last core in the system. PSCI lib does not do cache flush for the last core /cluster and does not follow the core / cluster power down sequence. This may cause issue in a system if the system is not standalone one ie if the system is a slave or node in a bigger system with other coherent masters/PEs.

Please suggest if the PSCI spec expected 'shutdown/reset/reset2' to deliberately skip the core/cluster shutdown sequence.

Otherwise in case it makes sense following is a patch to take care of this. https://review.trustedfirmware.org/#/c/TF-A/trusted-firmware-a/+/2364/ issue: https://developer.trustedfirmware.org/T566 Thanks Sandeep
