Subject: [PATCH 02/35] MIPS: ath79: separate common PCI code
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit
|
|
|
|
The 'pcibios_map_irq' and 'pcibios_plat_dev_init'
|
|
are common functions and only instance one of them
|
|
can be present in a single kernel.
|
|
|
|
Currently these functions can be built only if the
|
|
CONFIG_SOC_AR724X option is selected. However the
|
|
ath79 platform contain support for the AR71XX SoCs,.
|
|
The AR71XX SoCs have a differnet PCI controller,
|
|
and those will require a different code.
|
|
|
|
Move the common PCI code into a separeate file in
|
|
order to be able to use that with other SoCs as
|
|
well.
