715d8f7608 fsl_pci_init_port end-point initialization is broken
commit 70ed869e broke fsl pcie end-point initialization.
Returning 0 is not correct.  The function must return the first free
bus number for the next controller.

fsl_pci_init() must still be called and a bus allocated even if the
controller is an end-point.

01471d538f Revert "ppc/85xx/pci: fsl_pci_init: pcie agent mode support"
This reverts commit 70ed869ea5.

There isn't any need to modify the API for fsl_pci_init_port to pass the
status of host/agent(end-point) status.  We can determine that
internally to fsl_pci_init_port.  Revert the patch that makes the API
change.

70ed869ea5 ppc/85xx/pci: fsl_pci_init: pcie agent mode support
Originally written by Jason Jin and Mingkai Hu for mpc8536.

When QorIQ based board is configured as a PCIe agent, then unlock/enable
inbound PCI configuration cycles and init a 4K inbound memory window;
so that a PCIe host can access the PCIe agents SDRAM at address 0x0

* Supported in fsl_pci_init_port() after adding pcie_ep as a param
* Revamped copyright in drivers/pci/fsl_pci_init.c
* Mods in 85xx based board specific pci init after this change

a8b3e90f79 fsl_pci: create a SET_STD_PCI_INFO() helper wrapper
Recycle the recently added PCI-e wrapper used to reduce board
duplication of code by creating a similar version for plain PCI.

3e7b6c1f2d ppc/8xxx: Refactor code to determine if PCI is enabled & agent/host
Refactor the code into a simple bitmask lookup table that determines if
a given PCI controller is enabled and if its in host/root-complex or
agent/end-point mode.

Each processor in the PQ3/MPC86xx family specified different encodings
for the cfg_host_agt[] and cfg_IO_ports[] boot strapping signals.

0d3d68b25a driver/fsl_pci: Add fsl_pci_init_port function to initialize a PCI controller
fsl_pci_init_port can be called from board specific PCI initialization
routines to setup the PCI (or PCIe) controller.  This will reduce code
redundancy in most of the 85xx/86xx FSL board ports that setup PCI.

cb151aa2cf pci/fsl_pci_init: Fold fsl_pci_setup_inbound_windows into fsl_pci_init
Every platform that calls fsl_pci_init calls fsl_pci_setup_inbound_windows
before it calls fsl_pci_init.  There isn't any reason to just call it
from fsl_pci_init and simplify things a bit.
