Thanks for your clarification.

I did as suggested and implemeted psci_version (in the same way as ls1021xa):
https://pastebin.com/ZfJkN2HC

and now I get:

[    0.000000] psci: probing for conduit method from DT.
[    0.000000] psci: PSCIv1.0 detected in firmware.
[    0.000000] psci: Using standard PSCI v0.2 function IDs
[    0.000000] psci: MIGRATE_INFO_TYPE not supported.

Thanks
