Im not sure if i should rotavate it or throw top soil on.

Any one any ideas?

Til it up good! mix in some air, nutrients, fertilizer, and enough bags
of a good topsoil to cover the whole area at least a couple of inches.
Your work will be worth the effort if you put the time in now.

Consider Cover crops.

Consider raking out the "rubble" or it's all just a waste of time,
effort, and expense... no matter you bury rubble it'll keep working
its way to the surface, and that the soil is tilled/loosened much
faster... after the first year you'll be right back where you started,
only worse.
