## This file contains the differences to imx_v8_defconfig
## it is used to generate toradex_defconfig with the following command
##
## make imx_v8_defconfig
## scripts/kconfig/merge_config.sh -m .config arch/arm64/configs/toradex_imx_v8.config
## make savedefconfig && cp defconfig arch/arm64/configs/toradex_defconfig
