There may be someone out there who wishes to write some arbitrary data
to the same device where the bootloader is. As far as I know the barebox
update handler is able to write barebox images to the given device. I
don't know what happens with data that is not a barebox image. So I
would prefer to use the filetype checks first.

Will fix.
