New Revision: 276312
URL: https://svnweb.freebsd.org/changeset/base/276312

Log:
  MFC r276165, r276166:
  
    Define the old-school arm arch constants we still use internally based on
    the somewhat newer constants predefined by the compiler.  This will allow
    userland apps to use various machine/foo.h headers without CPUTYPE defined.
