      powerpc/fsl-booke: add the reg prop for pci bridge device node for T4/B4 · 9e2ecdbb
      Kevin Hao authored
      The reg property in the pci bridge device node is used to bind this
      device node to the pci bridge device. Then all the pci devices under
      this bridge could use the interrupt maps defined in this device node
      to do the irq translation. So if this property is missed, the pci
      traditional irq mechanism will not work.

      powerpc/fsl-pci: don't unmap the PCI SoC controller registers in setup_pci_atmu · 04aa99cd
      Kevin Hao authored
      In patch 34642bbb (powerpc/fsl-pci: Keep PCI SoC controller registers in
      pci_controller) we choose to keep the map of the PCI SoC controller
      registers. But we missed to delete the unmap in setup_pci_atmu
      function. This will cause the following call trace once we access
      the PCI SoC controller registers later.
