Description
Describe the bug
Unfortunate on the latest main (d54c308) none of available to me cortex m7 boards are able to start.
checked on stm32f746g & stm32h7b3i
using git bisect find out that reverting (on main) change introduced in #90305 fixes the issue.
Regression
- This is a regression.
Steps to reproduce
- cd zephyr/samples/hello_world
- rm -rf build/*; west build --board=stm32f746g_disco .
- west flash
- observe uart output
expected: boot banner and hello world text present
actual: nothing
back trace:

Additional Context
#90867 introduced revert update of the DTS configuration files. is my understanding right that it will require update of DTS files for all cortex-m7 targets?
