  Log:
  AMD's ELAN documentation says that you write to the SYS_RST register
  in the Memory Mapped Configuration Region (MMCR) to reset the CPU.
  If CPU_ELAN is set, try this first to reset the CPU before the
  traditional way.
  
  Without this change, my Compulab board powers down on 'reset' instead
  of rebooting.
