[PATCH v3 0/2] stacked overlay support

Overlay application has a shortcoming that it is not possible
to refer to labels that were defined by a previously applied
overlay.

This patchset fixes the problem by keeping around the labels
that each overlay contains.

It is dependent on two previously submitted patches
"Introduce fdt_get_path_len() method"
"Introduce fdt_setprop_placeholder() method"

Changes since V2:
* Rework to make application faster when using target-path
* Various cosmetic fixes

Changes since V1:
* Rework to remove reliance on malloc and FDT_PATH_MAX


Pantelis Antoniou (2):
  fdt: Allow stacked overlays phandle references
  tests: Add stacked overlay tests on fdtoverlay
