I think both Agustin's patch set and my mbigen one are in good shape
now if I didn't miss something, Rafael and Lorenzo already acked Agustin's
patch [1-2/3], I provided my review and test tags on them.

And Lorenzo said about the mbigen patches:
"I think this patch (and the FW that goes with it) is wrong, but the rest
of the series, in particular the IORT bits, are ok with me."
and I fixed the wrong patch and updated the _PRS to _CRS as Lorenzo
suggested in v8.

So, can I kindly ask that those patches (Agustin's patch set and my mbigen one)
be merged to 4.11 please? It's really important for Hisilicon (Hip06/Hip07) SoCs
which native NIC [1], SAS [2], USB and even the console on Hip07-D05 drivers
depend on those patches, and those platform are completely dead without
them if PCI is not enabled...

Thanks
