[PATCH 0/4] PCI: populate PCI host controller device nodes

[Sascha Hauer <s.hauer@pengutronix.de>]

PCI devices usually don't have and don't need a representation in the
device tree, but sometimes they do. This series adds support for adding
device nodes for PCI devices to the barebox live tree similar to what
Linux does with CONFIG_PCI_DYNAMIC_OF_NODES enabled. We also fixup the
Linux device tree with the PCI device nodes. This allows PCI device
drivers to register of_fixups for PCI devices: The barebox internal
PCI device now gets a device node (from the patched barebox live tree)
and it can use this node to find the corresponding device node in the
Linux device tree (possibly added by barebox as well).

In my case I do not need a PCI device driver to add a node to the
Linux tree. What I want to archieve is that a MAC address of a PCI
device that is initialized in a board specific way is forwarded to
Linux using the mac-address property. For this case there are is no
further code needed, the only piece missing is the creation of the
PCI device nodes added with this series.
