I have so far

        pci {
               compatible = "pci-x86";
               #address-cells = <3>;
               #size-cells = <2>;
               u-boot,dm-pre-reloc;
               ranges = <0x02000000 0x0 0x80000000 0x80000000 0 0x40000000
                         0x42000000 0x0 0xc0000000 0xc0000000 0 0x20000000
                         0x01000000 0x0 0x2000 0x2000 0 0xe000>;
       };

pci_init() makes the system hang.

WRT video I will try later when I see PCI initialized successfully.
