  • ad8f955da   m68k/Kconfig: Separate classic m68k and coldfire early ... Browse Code »

    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.

  • 0e152d805   m68k: reorganize Kconfig options to improve mmu/non-mmu selections ... Browse Code »

    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.
