The series is developed together with QEMU's: [Qemu-devel] [PATCH RFC 00/17] implement multiple primary busses for pc machines http://lists.gnu.org/archive/html/qemu-ppc/2015-01/msg00159.html (not related to ppc)
v1 -> v2: - Addressed Kevin O'Connor idea (Thanks!) to treat devices behind extra root PCI buses as belonging to Bus 0 for resource resizing and mapping.
The series fixes some issues when more than one root primary bus is present.
First patch scans all the bus range to find the extra root buses. Second patch extends memory and IO mapping for found buses.
Marcel Apfelbaum (2): fw/pci: scan all buses if extraroots romfile is present fw/pci: map memory and IO regions for multiple pci root buses
