* Enable ARM_APPENDED_DTB

  Typically the bootloader of a mackerel board does not support DT
  so this option is useful

* Add "rw" to command line

  This appears to be necessary for a successful NFS-root boot

I don't think memchunk is used outside of arch/sh, so it can be dropped from
this default cmdline?

Also, with DTB, there's little use for an in-kernel default command line since
you can give one with the dtb instead. Perhaps just drop it alltogether and
move it there?

Thanks, I'll see about making both of those changes and repost.
