Resolving Indirect Inclusion Conflicts in Kconfig Files

[PragatiGarg-eaton]

Hi All,
I have a scenario where the main Kconfig file includes the following sources:

# Main Kconfig file
source "Kconfig.zephyr"
source "Kconfig-1"

The Kconfig-1 file includes:

# Kconfig-1
source "\mcuboot\boot\zephyr\Kconfig-2"

And the Kconfig-2 file includes:

# Kconfig-2
source "Kconfig.zephyr"

This setup results in Kconfig.zephyr being included twice indirectly, causing conflicts.

I cannot remove Kconfig.zephyr from Kconfig-2 because Kconfig-2 is used in the mcuboot application, which can be built standalone as well. And neither "Kconfig.zephyr" from Main Kconfig file, since I need to provide two diff features based on user selection from a config.
In simpler words, I need to enable either of the feature using Config value from prj.conf, but it is causing conflicts.
Since, Kconfig lacks an 'if' condition model, so I can't make the inclusion conditional. Ref: https://docs.zephyrproject.org/latest/build/kconfig/tips.html#lack-of-conditional-includes

How can I resolve this conflict? Any help would be much appreciated.
