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 [,] . This column is case sensitive. In case there's a simple options like 256M_U_BOOT, it's plain expanded to "#define CONFIG_256M_U_BOOT" in config.h . In case there's an assignment, like "ram=8192", it's expanded to "#define CONFIG_RAM 8192" in config.h . There can also be multiple such options, then each is expanded to separate "#define CONFIG_xyz" statement.
Also, I had to add fallback logic, because each of the board variants has a distinct name. This led to the mkconfig #including incorrect board configuration file (<configs/whole-board-configuration-name.h> aka. the value in column one). I implemented a logic which checks if such file exists and if it does not, it includes<configs/board-name.h> aka. the value in third column.
