PCI: scan_bus[/pci@400/pci@1/pci@0/pci@0/pci@0] bus no 4
  * /pci@400/pci@1/pci@0/pci@0/pci@0/display@0
    create device, devfn: 0, type: display
    class: 0x30000 device name: 0000:04:00.0
    parse addresses (80 bytes) @ fff8001fffe34f40
  start: 84000000000, end: 840007fffff, i: 10
  start: 84000800000, end: 8400081ffff, i: 14
  start: 85100000000, end: 8510000007f, i: 18
  start: 84000000000, end: 8400000ffff, i: 30

so the BAR 6 the ROM bar is overlapping with BAR0.
and the ROM bar get rejected.

Looks like only the device BAR6 is not assigned form OF?

Thanks
