Is there an opposite for depends on in Kconfig? Which at least prints a warning when a specific CONFIG_* switch is set, which isn't compatible after the full configuration is written (.config) after a make *_defconfig?
My current problem:
I'm working on a new driver for the ARMv7-M Systick timer. There exists an old version, but this version lacks in some functionality and isn't ported to the new U-Boot device model (DM). When a new vendor use both driver, then this leads in an linker error.
So I want prevent with Kconfig to use my driver, when the old driver is selected.
Or any other suggestion how to solve this?
(This is a generic question for projects which use Kbuild/Kconfig as build system.)
The documentation states you can use depends on <expr>, so you can do:
depends on !OTHER_DRIVER
