[PATCH 0/7] add of_fdt_unflatten_tree

[Stephen Neuendorffer <stephen.neuendorffer@xilinx.com>]

	Currently, fdt blobs are handled solely at boot time.  However,
it may be useful to parse blobs into device trees after boot time.  For
instance, a PCIe device may have an FPGA which includes a device
tree.  This set of patches locally refactors the existing code to enable
this.

Patch 1 and 4-7 are the interesting bits.
Patch 2 and 3 provide the ability to use this code on x86, and are provided mostly for reference.

The non-early boot code has been compile-tested and executed on X86.

Stephen Neuendorffer (7):
  fdt: Add Kconfig for EARLY_FLATTREE
  arch/x86: Add support for device tree code.
  arch/x86: select OF and OF_FLATTREE
  fdt.c: Add non-boottime device tree functions
  fdt.c: Refactor unflatten_dt_node
  fdt.c: Reorder unflatten_dt_node
  fdt.c: Refactor unflatten_device_tree and add fdt_unflatten_tree
