   4 Subject: [PATCH 9/9] ARM: qcom: automatically select PCI_DOMAINS if PCI is
   5  enabled
   6
   7 If multiple PCIe devices are present in the system, the kernel will
   8 panic at boot time when trying to scan the PCI buses. This happens on
   9 IPQ806x based platforms, which has 3 PCIe ports.
  10
  11 Enabling this option allows the kernel to assign the pci-domains
  12 according to the device-tree content. This allows multiple PCIe
  13 controllers to coexist in the system.
