Introduce initial board support for the STM32MP257F-DK Discovery Kit. This includes: - Board metadata (board.yml, stm32mp257f_dk.yaml) - Base software configuration (Kconfig.stm32mp257f_dk) - CMake build integration (board.cmake) - Default configuration (stm32mp257f_dk_stm32mp257fxx_m33_defconfig) - Minimal device tree (stm32mp257f_dk_stm32mp257fxx_m33.dts) - Initial documentation and image for the stm32mp257f_dk board. - OpenOCD configuration files for debugging support.

There was a problem hiding this comment.
that's three (!) pages of information that really doesn't belong to Zephyr documentation. Please trim it down (and there are some sub-bulllet list that are missing preceding blank line anyway and don't render correctly)
