Huang Ying <ying.huang@intel.com> created the debugfs file for boot_params.
His first version patch tried sysfs, but sysfs is not designed for such
binary blobs so finally it go to debugfs.

Any idea for this is welcome, till now I have no better idea for such kind
of data. We should have another *fs instead of using debugfs.

Thanks
