Question

I saw board directory in zephyr. I found Kconfig, Kconfig.board and Kconfig.deconfig files. What is purpose all these files ? ( see board files of nRF5340DK or thingy53 )

Hi, See https://docs.zephyrproject.org/latest/hardware/porting/board_porting.html: 
 Kconfig.board , Kconfig.defconfig , plank_defconfig : software configuration in Configuration System (Kconfig) formats. This provides default settings for software features and peripheral drivers.
