I guess you have non-PSCI firmware too? In any case, unless things have changed, upstream is only supporting spin-table or PSCI for arm64. So please combine this with the rest of the cpu nodes.

This was copied from older Tegras - we might have had some systems in the past with non-PSCI firmware, but certainly don't have that anymore. I'll combine the nodes.
