m68knommu: create config options for CPU classes
There are 3 families of CPU core types that we support in the m68knommu architecture branch. They are . traditional 68000 . CPU32 (a 68020 core derivative without MMU or bitfield instructions) . ColdFire It will be useful going forward to have a CONFIG_ option defined for each type. We already have one for ColdFire (CONFIG_COLDFIRE), so add for the other 2 families, CONFIG_M68000 and CONFIG_MCPU32. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

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
|
||||
based on the 68020 processor. For the most part it is used in
|
||||
System-On-Chip parts, and does not contain a paging MMU.

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.
