Following the instruction from https://github.com/STMicroelectronics/meta-st-stm32mp/blob/thud/recipes-kernel/linux/linux-stm32mp/README.HOW_TO.txt
* Configure on a build directory (different of kernel source code directory) Here for example, build directory is located at the same level of kernel source code $> cd <directory to kernel source code> $> mkdir -p ../build
$> make ARCH=arm O="$PWD/../build" multi_v7_defconfig fragment*.config
