+Subject: [PATCH 08/47] MIPS: ath79: add a common PCI registration function
+
+The current code unconditionally registers the AR724X
+specific PCI controller, even if the kernel is running
+on a different SoC.
+
+Add a common function for PCI controller registration,
+and only register the AR724X PCI controller if the kernel
+is running on an AR724X SoC.
