Hi,

This patchset adds a generic rule for applying overlays using fdtoverlay
tool and then updates unittests to get built statically using the same.

V10->V11:
- Update patch 4/5 to fix checkpatch warning on spaces and tabs.
- Added Acked-by from Masahiro for patch 2/5.

V9->V10:
- Add a new patch to allow .dtso files.
- Update 2/5 to be more efficient and also generate symbols for base
  files automatically.
- No need to add lines like DTC_FLAGS_foo_base += -@ in patch 5/5.
- Add Ack by Masahiro for 1/5.

V8->V9:
- Added some comment in patch 3/4 based on Frank's suggestions.

V7->V8:
- Patch 1 is new.
- Platforms need to use dtb-y += foo.dtb instead of overlay-y +=
  foo.dtb.
- Use multi_depend instead of .SECONDEXPANSION.
- Use dtb-y for unittest instead of overlay-y.
- Rename the commented dtb filess in unittest Makefile as .dtbo.
- Improved Makefile code (I am learning a lot every day :)

V6->V7:
- Dropped the first 4 patches, already merged.
- Patch 1/3 is new, suggested by Rob and slightly modified by me.
- Adapt Patch 3/3 to the new rule and name the overlay dtbs as .dtbo.

Does not apply to 5.12-rc2 because of a dependency on a patch to
scripts/Makefile.lib.  That patch has been merged by Linus
somewhere between -rc2 and -rc3.  I had a working version
between -rc2 and -rc3 at commit e6f197677b2e that does have
the required patch, so that is the version I used to test
this series.

There is still confusion caused by the contortions that unittest
goes through to mis-use base DTBs vs overlay DTBs, so _after_
this series is merged by Rob, I will poke around and see if
I can change unittest so that it does not look like it is
mis-using DTBs and overlay DTBs.

I was based right over the 5.12-rc2 tag.

git log --oneline v5.12-rc2..origin/master -- scripts/Makefile.lib

gives no results to me.

I have tried both Linus' tree and linux-next, and I don't see this
commit.

Rob, can you please apply patch 1-2,4-5 from this series ? I will send
a new version of the patch 3/5 (related to .dtso) separately.

I don't know why I failed.  Given your report, I went back to
v5.12-rc2 and the patch series applies fine.

Either way, my tags are ok.

Sorry about that, the commit id I gave was after applying the patch
series.  The commit id I should have reported is 144c79ef3353.
