Paul Burton 62be393423 hw: xilinx-pcie: Add support for Xilinx AXI PCIe Controller
Add support for emulating the Xilinx AXI Root Port Bridge for PCI
Express as described by Xilinx' PG055 document. This is a PCIe
controller that can be used with certain series of Xilinx FPGAs, and is
used on the MIPS Boston board which will make use of this code.

  removed returning on !level,
  updated IRQ connection with GPIO logic,
  moved xilinx_pcie_init() to boston.c
  replaced stw_le_p() with pci_set_word()
  and other cosmetic changes]

Alexander Graf 4d8fde1126 pci: Add generic PCIe host bridge
With simple exposure of MMFG, ioport window, mmio window and an IRQ line we
can successfully create a workable PCIe host bridge that can be mapped anywhere
and only needs to get described to the OS using whatever means it likes.

This patch implements such a "generic" host bridge. It handles 4 legacy IRQ
lines. MSIs need to be handled external to the host bridge.

This device is particularly useful for the "pci-host-ecam-generic" driver in
Linux.

Michael S. Tsirkin cbef02f819 dec.c - move to pci-bridge
Looks like dec.c is in pci-host by mistake.
Moving it over to pci-bridge.
