[PATCH 0/8] Broadcom iProc PCIe fixes and outbound mapping support

[Ray Jui]

This patch series contains various fixes and outbound mapping support for
the Broadcom iProc PCIe driver. Some of the critical fixes include 1) fix of
PCIe core reset logic and therefore remove its dependency on the bootloader;
2) improved link detection logic that works for more iProc based SoCs.

This patch series also adds the outbound address mapping support. While
outbound address mapping support is not required on chips like North Star,
Cygnus, and etc., some of the newer iProc based chips like North Star 2 require
this support to properly map the AXI address into the address used in the iProc
PCIe core

This patch series is constructed based on Linux v4.3-rc1 (with workaround to
disable calls to pci_read_bridge_bases in pci/probe.c that breaks some of the
ARM based PCIe devices including iProc)

This patch series is tested on the following platforms with an Intel e1000e
based PCIe x1 NIC card:
- ARM32 based Cygnus BCM958305K Wireless Audio board
- ARM64 based North Star 2 SVK board
