      [ARM] 4736/1: Export atags to userspace and allow kexec to use customised atags · 4cd9d6f7
      Richard Purdie authored
      
      
      Currently, the atags used by kexec are fixed to the ones originally used
      to boot the kernel. This is less than ideal as changing the commandline,
      initrd and other options would be a useful feature.
      
      This patch exports the atags used for the current kernel to userspace
      through an "atags" file in procfs. The presence of the file is
      controlled by its own Kconfig option and cleans up several ifdef blocks
      into a separate file. The tags for the new kernel are assumed to be at
      a fixed location before the kernel image itself. The location of the
      tags used to boot the original kernel is unimportant and no longer
      saved.
