[v1] GitLab CI cleanup & improvements for Arm

[PATCH 5/9] automation: qemu-smoke-arm32.sh: Modify script to use ImageBuilder

Posted by Michal Orzel 3 years, 4 months ago

Take an example from arm64 qemu test scripts and use ImageBuilder
to generate u-boot script automatically. Calculating the addresses
manually is quite error prone and also we will be able to benefit
from using ImageBuilder when adding domUs to this test in the future.

Install and use u-boot from the debian package.
Modify the script so that binaries are loaded from u-boot via tftp.

Great patch! It makes the test a lot better!

This is missing dtuart=/pl011@9000000 compared to the original

"bootm" because "booti" is not available on arm32, right?

Actually this is not needed because we always have stdout-path defined in chosen to point to /pl011@...
but I can add this.
