The Freescale (was Motorola) 68000 CPU is the first generation of
|
|
the well known M68K family of processors. The CPU core as well as
|
|
being available as a stand alone CPU was also used in many
|
|
System-On-Chip devices (eg 68328, 68302, etc). It does not contain

a paging MMU.

The Freescale (was then Motorola) CPU32 is a CPU core that is

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 say Y here the kernel will use a 4Kb stacksize for the

kernel stack attached to each process/thread. This facilitates

|
running more threads on a system and also reduces the pressure
|
|
on the VM subsystem for higher order allocations.

Define the address that RAM starts at. On many platforms this is

help

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