Call this powerpc-ofw-... Does it even contain something we use in Linux
at all ? Last I looked we only used the common one right ? Also it's
format afaik is defined in the CHRP bindings so it's not generic OFW
stuff, hence the powerpc prefix.

Same deal, call that powerpc-common

Sure. Will change it to powerpc prefix.

sprintf(name, "unknown-%s-%lld", psname, id);

Do we expose anything else or keep it hidden ?

We are exposing oops, rtas, of-config and common partition of nvram.

Cheers,
