      image: Add support for signing of FIT configurations · 4d098529

      While signing images is useful, it does not provide complete protection
      against several types of attack. For example, it it possible to create a
      FIT with the same signed images, but with the configuration changed such
      that a different one is selected (mix and match attack). It is also possible
      to substitute a signed image from an older FIT version into a newer FIT
      (roll-back attack).
      
      Add support for signing of FIT configurations using the libfdt's region
      support.
      
      Please see doc/uImage.FIT/signature.txt for more information.

      Add a structure to describe an algorithm which can sign and (later) verify
      images.
