While his comments on v1 have been addressed, he has not had a chance to acknowledge the solutions. I appreciate Marc's holiday is unfortunately timed. I also have an open concern with the binding with regard to the orthogonality of GICV GICH and the MSI registers. Suravee, do you need this urgently for v3.17? I was under the impression that we wouldn't have full PCIe support by then. Cheers, Mark.
