tsar_boot: improving configuration infrastructure

  • Using hard_config.h which respects the same sintax that the hard_config.h file of all TSAR platforms. This file can be then generated by the GIET-VM genmap tool or written manually.
  • All peripheral drivers have been moved to a drivers directory and they are compiled as a static library. This allows GCC to only include in the final .ELF the object files of used peripherals and not all of them.
  • Example hard_config.h and ldscripts have been introduced in the conf directory.
  • Improving comments in all files
