#1687736 — Makefile in libfdt shows non-existent files

Message-ID<u3jB7-2JB-3@gated-at.bofh.it>
Hi Rob,

I was trying the latest dtc as on Linux 4.12 for device tree overlay. On 
the latest kernel, I see the following commit:

commit 6f05afcbb031722ec1eff77dde188ff2edf8940e ("scripts/dtc: Update to 
upstream version 0931cea3ba20")

This seems to pull in various upstream dtc commits for dtc overlay 
including:

commit 0cdd06c5135bd9f46853c2f58ad2ac91b0fa87f3 ("libfdt: Add overlay 
application function")

The upstream commit introduces libfdt/fdt_overlay.c, but this file is 
not reflected in the kernel. Similar case is also seen for 
libfdt/fdt_addresses.c.

Can you help confirm if these files should indeed have been pulled into 
the kernel and if anything else is missing from DTC side.

Thanks,

Kyle

Indeed. The update-dtc-source.sh script has an explicit list of files to copy.

Yes, though the kernel doesn't need them so it doesn't matter too much.
