The Snapdragon 778G (SM7325) / 778G+ (SM7325-AE) / 782G (SM7325-AF)
is software-wise very similar to the Snapdragon 7c+ Gen 3 (SC7280).

It uses the Kryo670.

This is a meaningless marketing name. As you mentioned in your
reply, cpu0-3 and cpu4-7 are wholly different (maybe cpu7 even
has a different MIDR part num?), we should do something about it :/

Please post the output of `dmesg | grep "Booted secondary processor"`
