This config is based on stm32mp15_basic_defconfig and adds the necessary options to be able to boot a STM32MP157C-DK2 dev board.

For information, stm32mp157c-dk2 board is already supported by stm32mp15_basic_defconfig without the need of a specific defconfig (I am using it every day).
You just need to specify the used devictree with the generic Makefile parameter DEVICE_TREE=stm32mp157c-dk2
For support details: ./doc/board/st/stm32mp1.rst Or https://wiki.st.com/stm32mpu/wiki/STM32MP15_U-Boot
example
# make stm32mp15_basic_defconfig # make DEVICE_TREE=stm32mp157c-dk2 all
Or
# export KBUILD_OUTPUT=../build/stm32mp15_basic # export DEVICE_TREE= stm32mp157c-dk2 # make stm32mp15_basic_defconfig # make all
CONFIG_DEFAULT_DEVICE_TREE only provide the default device tree used when DEVICE_TREE is absent.
What it is the need to this new defconfig ? U-Boot size optimization for DK2 only ?
PS: If something is missing in stm32mp15_basic_defconfig/stm32mp15_trusted_defconfig it should be added in this generic target common for all ST supported boards.
