  • libblock/src/bdbuf.c, libmisc/capture/capture-cli.c, libmisc/capture/capture.c, libmisc/mw-fb/mw_uid.c, rtems/include/rtems/rtems/support.h, score/Makefile.am, score/include/rtems/score/tod.h, score/src/coretod.c, score/src/coretodtickle.c: Eliminate all public use of TOD conversion routines. Eliminate _TOD_Microseconds_per_tick and let every place use the field directly from the Configuration Table. This required moving some methods from macros to bodies.
  • score/src/coretodmsecstoticks.c, score/src/coretodtickspersec.c, score/src/coretodusectoticks.c: New files.
