Yes!

Can you put this into stemmy_defconfig? > diff --git a/board/ste/stemmy/Kconfig b/board/ste/stemmy/Kconfig > index b890ba51cb03..e891ddf9f8b2 100644 > --- a/board/ste/stemmy/Kconfig > +++ b/board/ste/stemmy/Kconfig > @@ -9,4 +9,10 @@ config SYS_VENDOR > config SYS_CONFIG_NAME > default "stemmy" > > +config DEFAULT_DEVICE_TREE > + default "st/ste-ux500-samsung-janice" > + > +config OF_LIST > + default "st/ste-ux500-samsung-codina st/ste-ux500-samsung-codina-tmo > st/ste-ux500-samsung-gavini st/ste-ux500-samsung-golden > st/ste-ux500-samsung-janice st/ste-ux500-samsung-kyle > st/ste-ux500-samsung-skomer" > + > endif I don't mind adding this here, but I'm also not sure if there is any advantage compared to adding this directly in stemmy_defconfig?
