This is a preliminary set of patches to add kexec support for m68k.

  - [PATCH 1/3] m68k: Add preliminary kexec support
  - [PATCH 2/3] m68k: Add support to export bootinfo in procfs
  - [PATCH 3/3] [RFC] m68k: Add System RAM to /proc/iomem

Notes:
  - The bootinfo is now saved and exported to /proc/bootinfo, so kexec-tools
    can read it and pass it (possibly after modification) to the new kernel.
    This is similar to /proc/atags on ARM.

  - I based [PATCH 3/3] on the PowerPC version, but it's no longer needed as we
    now get this information from the bootinfo.
    Does anyone think this is nice to have anyway?

It seems kexec/kdump on ppc don't use /proc/iomem anymore, and only rely on
/proc/device-tree these days?

I think thats entirely a matter for the m68k kernel maintainers to decide.
But my personal opinion is that it is nice not to add it if it isn't needed.
