Hi guys,

I have a question regarding to sharing generic OF pcie driver between
two architectures MB and ARM Zynq.
Is drivers/pci/pcie location good for it?
Make no sense to have the same driver in two locations.
Is using readl/writel IO functions in this driver the best option
which we can have?
Or is there any other recommendation?

Also just want to check if it is correct to use pcie device_type.
The rest should be the same with pci description:
(http://devicetree.org/MPC5200:PCI#PCI_Address_Translation).

Yes. device_type may be deprecated, but the PCI binding predates that.
PowerPC uses pcie in the device type. arch/powerpc/kernel/of_platform.c

Some of that powerpc DT PCI support code really should be made generic.
