Xen is missing fdt overlay functionalities. FDT overlay is required for changing
the device tree nodes during run-time.
fdt_overlay.c file is copied from Linux tree's following patch:
commit: 6e9c9686d826564f44c93cdd6f111b1c0a9dc224
scripts/dtc: Update to upstream version v1.6.0-31-gcbca977ea121
This patch and the next one add quite a bit of code in libfdt. The
directory xen/common/libfdt is pretty much a snapshot of v1.4.0 (we
tweaked the Makefile and import 2 bug fixes).
So I would prefer if we re-sync our directory with the one in
https://github.com/dgibson/dtc.git. v1.6.1 seems a good candidate.
