Also I hope they are not using Arm Architecture/CPU service range of FID and they use SiP/OEM service range. From what I understand, you need a generic debug FS for all SMCCC instead of just PSCI in your case. The latter must cover PSCI as well while the reverse must not happen. So if we need this beyond PSCI FID range, better you have it as generic SMCCC debug FS.
