  Log:
  RTC_TIMR's RTC_SEC field is BCD.  That makes it unsuitable for
  GetSeconds().  Instead, use CRTR register shifted right 15.  This
  gives us a range of 32 seconds we can do for timeout.
  
  Shift to using == rather than < or > for calculating the timeout,
  since if we can't read the ST_CTRT register twice in a second we have
  even bigger problems to worry about, and == deals with the 'wrap'
  issue.
  
  This lets me type at the boot2 prompt again!  Woo Hoo!
