Unfortunately it won't be enough. Indeed after speaking with Marvell engineers we realized that the MPIC didn't work as we expected. As it is written in the following patch: the MPIC, unlike the GIC, allows several CPUs to acknowledge the same global interrupt. I joined the patch to this email, you can apply it on top of your mvebu/boards or you can squash it with the previous patch.
