> To use an existing file as .config for a project, it needs to be
> validated with 'make oldconfig'. If the file does not match all the
> configuration entries of the project, the user will be prompted to
> select the values for the new entries.
>
> Historically, 'yes "" | make oldconfig' was used to silently select the
> default values for new entries. But this does not work well with the
> Linux kernel, as it will not select the correct option when configuring
> tristate choice entries.
>
> The Linux kernel has added a 'oldnoconfig' target, since renamed
> 'olddefconfig', that will work correctly, but this target does not exist
> in all projects that rely on the kconfig workflow.
>
> Update buildroot to use 'oldnoconfig' when available, and fallback to
> the default method otherwise.
>
> Changelog:
> v1: creation as a package option
> v2: try 'make oldnoconfig' before 'yes "" | make oldconfig' and remove
>     the option
> v3: Remove useless $(call ...), and factorize the make command
>
> Romain Izard (3):
>   core/pkg-kconfig: Factorize make commands
>   core/pkg-kconfig: Do not use $(call ...) without parameters
>   core/pkg-kconfig: Use oldnoconfig when possible
