74169f98c7 m68knommu: add support for configuring a Freescale M5373EVB board
Add a configuration switch for supporting the Freescale M5373EVB board.
It is based on the newly added ColdFire 537x CPU support.

5143661ff8 m68k: clean up unused "config ROMVECSIZE"
Kconfig symbol ROMVECSIZE is unused since commit
f84f52a5c1 ("m68knommu: clean up linker
script"). Let's clean up its Kconfig entry too.

ef9240f482 m68k: drop "select EMAC_INC"
Somehow this select statement managed to squeeze itself between commit
0e152d8050 ("m68k: reorganize Kconfig
options to improve mmu/non-mmu selections") and commit
95e82747d6 ("m68k: drop unused Kconfig
symbols"). Whatever happened, there is no Kconfig symbol named EMAC_INC.
The select statement for that symbol is a nop. Drop it.

ad8f955daf m68k/Kconfig: Separate classic m68k and coldfire early
While you can build multiplatform kernels for machines with classic
m68k processors, you cannot mix support for classic m68k and coldfire
processors. To avoid such hybrid kernels, introduce CONFIG_M68KCLASSIC
as an antipole for CONFIG_COLDFIRE, and make all specific processor
support depend on one of them.
All classic m68k machine support also needs to depend on this.

The defaults (CONFIG_M68KCLASSIC if MMU, CONFIG_COLDFIRE if !MMU) are
chosen such to make most of the existing configs build and work.

0e152d8050 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.
