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. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
