This change adds PCIe support to IPQ806x based platforms. The driver is actually cherry-picked from the following LKML thread: *https://lwn.net/Articles/643086/ (patches 110-111) We also add here an additional fix to support multiple PCI controllers on the same platform (patch 112), and to patch the ap148 & dbs149 DTS files (patch 113).

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