some changes to KERNEL_DEVICETREE as the dtb layout has changed to
support overlays. This change also makes us ready to support kernel 4.x

least I get problems during compile step with above change (I'm building
for rpi2). So are your sure '${B}/arch/arm/boot/dts/overlays' isn't
needed during compile? I tried with changing above from append to
prepand instead and then it worked fine for me (when building 3.18
kernel). (from log.do_compile, complete log can be found at:

some "pebcak" from my side, since I was using an old sstate, but
according to my history I did 'cleanall' before I got the problem. But
will re-try this on a completely new build without any old savings (it
will take some time to test however..). What struck me was that the
failure occurred in do_compile (from what I can tell the failure in my
logs occur before your _append had been able to do anything about it?).
I will analyse the run.do_compile if the failure occurs again and see if
that make any sense. I will let you know if the problem occurs again.
But since both you and Herve haven't seen any problem I guess it's
something I'm doing wrong..

I
think I know what the problem is. Are you building using poky:fido?
Because I found a very interesting commit in this area from May that
isn't included in 'fido' from what I can see. d2e26ef kernel: Build DTBs
early ... kernel: Build DTBs early Pull out the compilation of the DTB
blobs right after the kernel's own do_compile function finishes. This
makes them available just in time for the kernel image construction
functions. ... This is also confirmed in the below run.do_compile log.
So I guess a my suggestion with a _prepend instead will solve the
problem. 

do_compile() {
 kernel_do_compile
 if test -n "
