| 4 | Subject: [PATCH 33/69] 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. |
