New Revision: 336662
URL: https://svnweb.freebsd.org/changeset/base/336662

Log:
  Deprecate jedec_ts(4) and point users to jedec_dimm(4) instead
  
  jedec_dimm(4) is a superset of the functionality of jedec_ts(4). Mark
  jedec_ts(4) as removed in FreeBSD 12, and include a pointer to the migration
  instructions in the jedec_dimm(4) manpage, in both the jedec_ts(4) code and
  the jedec_ts(4) manpage. Add a note to the jedec_dimm(4) manpage about the
  fact that it is a superset of jedec_ts(4).
  
  This change will be MFCed to stable/11 and stable/10; the followup change
  to actually remove jedec_ts(4) from -HEAD will not.
