defconfig, only enabling hardware device drivers (and related options) and FIT IMAGE on top of the generic_defconfig and other snippets in this directory, e.g. have you seen the other board config examples here? https://git.linux-mips.org/cgit/linux-mti.git/tree/arch/mips/configs/generic?h=eng If specific generic kernel features are desired we should probably consider whether it makes sense to add them to the generic_defconfig so other generic boards can benefit.
