+ The Freescale (was Motorola) M68K family of processors implements
+ the full 68000 processor instruction set.
+ The Freescale ColdFire family of processors is a modern derivitive
+ of the 68000 processor family. They are mainly targeted at embedded
+ applications, and are all System-On-Chip (SOC) devices, as opposed
+ to stand alone CPUs. They implement a subset of the original 68000
+ processor instruction set.
+ If you anticipate running this kernel on a computer with a classic
+ MC68xxx processor, select M68KCLASSIC.
+ If you anticipate running this kernel on a computer with a ColdFire
+ processor, select COLDFIRE.
