There are some boards where it's not currently possible to detect all board information at runtime, therefore I introduced a new column called "options" to boards.cfg .

This column can contain multiple options, separated by comma [,] . In case there's a simple options like 256M_U_BOOT, it's plain expanded to "#define CONFIG_MK_256M_U_BOOT" in config.h . In case there's an assignment, like "RAM=8192", it's expanded to "#define CONFIG_MK_RAM 8192" in config.h . There can also be multiple such options, then each is expanded to separate "#define CONFIG_MK_xyz" statement.

I also added fallback logic, in case the include/configs/Target.h config file doesn't exist, include/configs/BOARD NAME.h is used.
