test_abootimg is extended to include the testing of boot images
version 4. For this, boot.img and vendor_boot.img have been
generated using mkbootimg tool with setting the header
version to 4.

This tests:
- Getting the header version using abootimg
- Extracting the load address of the dtb
- Extracting the dtb start address in RAM

Running test:
$ ./test/py/test.py --bd sandbox --build -k test_abootimg

Alright, so I don't know where the failure starts, exactly. And to make
testing this easier, there's currently the
trini/u-boot-gitlab-ci-runner:jammy-20230126-07Feb2023 container you can
use to replicate my problem. The problem is that while this test passes
in CI, with GCC, with Clang it fails, consistently:
https://source.denx.de/u-boot/u-boot/-/jobs/572239#L284
and I'm not quite sure why. I hope that building sandbox with clang and
also just trying these features out interactively will fail too, and so
debugging this will be less of a problem.

Hello Tom,

I have investigated this issue, clang has a strange behavior in:

* abootimg_get_dtb_load_addr() : cmd/abootimg.c
* android_image_get_dtb_by_index() : boot/image-android.c

That is probably linked to some sort of optimization clang does.

However, The fail is not reproducible using clang-15 and clang-16 and also
not reproducible when turning off clang optimizations.

I suggest using clang-15 to run the test or I can remove all optimizations

on the related functions if clang-14 is used.
Thanks for investigating.  I see that 15 is now considered stable, so
I'll update the next branch for that, then re-take this series.


Hello Tom,

Thank you.

I am a bit confused, do you mean that you will apply this series after clang-15 update?

Best regards,

Safae
