/* The intention is that we only set up the UPMs in ROM start, be it actual
 * ROM application start or Stub ROMs that we built from the same sources.
 * 
 * The alternative approach - in which we have reliability doubts - is to
 * program the UPMs with *old* timing data in StubROM start, then
 * *reprogram* them with *new* timing data in RAM start - and of course
 * program with *new* timing data in plain ROM application start.
 * (Re-programming from new to new timing data fails - hence the suspicion
 * of reprogramming _at_all_, hence this private configuration)
 * 
 * With CYGPRI_RAM_START_PROGRAMS_UPMS left undefined, the former behaviour
 * - programming the UPMs exactly once - is obtained.  Define it to get the
 * latter, untrusted behaviour.
