What does this have to do with corenet?

No need for the <SoC> part.  As we previously discussed, the only
purpose of this node is backwards compatibility with the U-Boot MAC
address fixup -- if U-Boot doesn't look for the <SoC> version, then
don't complicate things.

Though, I can't find where U-Boot references this node.  Are you sure
it's not using the ethernet%d aliases like everything else, in which
case why do we need this node at all?
