This makes sense, I guess (though it currently leaves us in the
odd position that we have separate a object for v6m, but the v7m
object handles both v7m and v8m...)

This is presumably just a code movement and rename, but it's a bit
hard to confirm that. Could you split it out into its own patch, please?
