To execute the conversion away from board specific header files, Kconfig menus have been implemented for all KM boards and additionally for those having an ARM architecture. For the moment, the preprocessor definitions stay in the headers. The boolean types, however, needed a modification (#define CONFIG_* 1). The default configuration files of some boards required an update in order to not change the currently defined values of the configurations.
