Hello all,
This is a series based on my patch here[0]. As suggested by Rob
I've resurrected Frank's patch and appended it to mine as a series.
First patch here is my original patch, 3rd is Frank's patch but with
the unittest changes pulled out into the 2nd patch. That was re-worked
moving the source building macro into scripts/Makefile.lib.
Patches 4, 5, and 6 are an attempt at renaming all the existing DTB
overlays. Split out by platform so they could be taken by platform
maintainers or if easier ACK'd here and taken all together.
This should cover all the DTB overlays so we can remove the old .dts
rule for overlays and make .dtso the only supported way, let me know
if we want that this cycle and I can post that too.
Thanks,
Andrew
Changes from v1[1]:
- Added patch to rename pi433 overlay.
- Cleaned wording on patch 4-6.
- Collected some ACKs

kbuild: Allow DTB overlays to built into .dtbo.S files
broke the build reproducibility / no-op builds.
Before:
2+ execution of `make` on non-changed tree did nothing
Now:
Each run of `make` (even without a single bit changed) restarts vmlinux
rebuild.
Please, revert or fix.
I do not see this behavior. What config are you using?
Not sure how this patch could be the root cause, it only adds
a build target/rule, but doesn't actually use it anywhere yet..
