[PATCH V6 3/3] powerpc/fsl-pci: Unify pci/pcie initialization code
Jia Hongtao

Fri Aug 10 18:19:36 EST 2012
We unified the Freescale pci/pcie initialization by changing the fsl_pci
to a platform driver. In previous PCI code architecture the initialization
routine is called at board_setup_arch stage. Now the initialization is done
in probe function which is architectural better. Also It's convenient for
adding PM support for PCI controller in later patch.
We also change the way of determining primary bus for fitting platform
driver. Thanks to the proposal from Ben. Please refer to the link below:
https://lists.ozlabs.org/pipermail/linuxppc-dev/2012-June/098586.html
Now we registered pci controllers as platform devices. So we combine two
initialization code as one platform driver.

Changes for V6:
- Fix "isa_io_base could not be zero" bug. Thanks to Ben.
- Determining primary by looking for ISA node does not work for ge_imp3a.
It's fixed by adding ISA node to its devied tree.
