Changes (by Quozl):

  * next_action:  design => package


 The test was extended to several thousand cycles and the results

 Fixed as much as possible in
 [http://tracker.coreboot.org/trac/openfirmware/changeset/3649 svn 3649].
 This should prevent the year 6500 symptom, and several others, but not all
 possible symptoms.  A brick tested build is
 [http://dev.laptop.org/~quozl/q3c13jb.rom q3c13jb.rom].

 The XO-1.5 cannot detect loss of RTC data using the RTC itself.  RTC anti-
 rollback should be deployed in situations where RTC data is critical.
