In pci_read_bridge_mmio_pref(), no prefetchable window (64bits+pref) is populated if bit PCI_PREF_RANGE_TYPE_64 (0x1) isn't set on PCI config register (PCI_PREF_MEMORY_BASE, 0x24). During the resource resizing and assigning stage in PCI core, all resources including 64-bits prefetchable resources will be covered by 32-bits bridge window.
Yeah ok, that's it, thanks ! Cheers, Ben.
