Hi Jason,
thanks for taking this patch. 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.
Thanks,
Gregory
