21 The Freescale (was Motorola) 68000 CPU is the first generation of
22 the well known M68K family of processors. The CPU core as well as
23 being available as a stand alone CPU was also used in many

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
45 processor instruction set.

667 Typically on m68k systems the kernel will not start at the base
668 of RAM, but usually some small offset from it. Define the start
669 address of the kernel here. The most common setup will have the
670 processor vectors at the base of RAM and then the start of the
671 kernel. On some platforms some RAM is reserved for boot loaders
672 and the kernel starts after that. The 0x400 default was based on
673 a system with the RAM based at address 0, and leaving enough room
674 for the theoretical maximum number of 256 vectors.
