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.
