m68k: reorganize Kconfig options to improve mmu/non-mmu selections 

The current mmu and non-mmu Kconfig files can be merged to form
a more general selection of options. The current break up of options
is due to the simple brute force merge from the m68k and m68knommu
arch directories.

Many of the options are not at all specific to having the MMU enabled
or not. They are actually associated with a particular CPU type or
platform type.

Ultimately as we support all processors with the MMU disabled we need
many of these options to be selectable without the MMU option enabled.
And likewise some of the ColdFire processors, which currently are only
supported with the MMU disabled, do have MMU hardware, and will need
to have options selected on CPU type, not MMU disabled.

This patch removes the old mmu and non-mmu Kconfigs and instead breaks
up the configuration into four areas: cpu, machine, bus, devices.

The Kconfig.cpu lists all the options associated with selecting a CPU,
and includes options specific to each CPU type as well.

Kconfig.machine lists all options associated with selecting a machine
type. Almost always the machines selectable is restricted by the chosen
CPU.

Kconfig.bus contains options associated with selecting bus types on the
various machine types. That includes PCI bus, PCMCIA bus, etc.

Kconfig.devices contains options for drivers and driver associated
options.

If you say Y here, it will be possible to use a serial port as the

kernel messages and warnings and which allows logins in single user
mode). This could be useful if some terminal or printer is connected
to that serial port.
Even if you say Y here, the currently visible virtual console
(/dev/tty0) will still be used as the system console by default, but
you can alter that using a kernel command line option such as
"console=ttyS1". (Try "man bootparam" or see the documentation of
your boot loader (lilo or loadlin) about how to pass options to the
kernel at boot time.)
If you don't have a VGA card installed and you say Y here, the
kernel will automatically use the first serial line, /dev/ttyS0, as
system console.

MicroChannel Architecture is found in some IBM PS/2 machines and

The Freescale (was Motorola) 68000 CPU is the first generation of
the well known M68K family of processors. The CPU core as well as

cards, you need to say Y here and also to "CardBus support" below.
To use your PC-cards, you will need supporting software from David
Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>

On some CPU's you do not need to know what the core CPU clock
frequency is. On these you can disable clock setting. On some
traditional 68K parts, and on all ColdFire parts you need to set
the appropriate CPU clock frequency. On these devices many of the

Define the CPU clock frequency in use. This is the core clock
frequency, it may or may not be the same as the external clock
crystal fitted to your board. Some processors have an internal
PLL and can have their frequency programmed at run time, others
use internal dividers. In general the kernel won't setup a PLL
if it is fitted (there are some exceptions). This value will be

If you say Y here, it will be possible to use a serial port as the
system console (the system console is the device which receives all
kernel messages and warnings and which allows logins in single user
mode). This could be useful if some terminal or printer is connected
to that serial port.
Even if you say Y here, the currently visible virtual console
(/dev/tty0) will still be used as the system console by default, but
you can alter that using a kernel command line option such as
"console=ttyS1". (Try "man bootparam" or see the documentation of
your boot loader (lilo or loadlin) about how to pass options to the
kernel at boot time.)
If you don't have a VGA card installed and you say Y here, the
kernel will automatically use the first serial line, /dev/ttyS0, as
system console.
If unsure, say N.
