  41           The Freescale ColdFire family of processors is a modern derivitive
  42           of the 68000 processor family. They are mainly targeted at embedded
  43           applications, and are all System-On-Chip (SOC) devices, as opposed
  44           to stand alone CPUs. They implement a subset of the original 68000
