[resent][PATCH 0/3] mkimage: allow to specify signing algorithm

[Jan Kiszka <jan.kiszka@siemens.com>]

[resent as requested by Simon]

Another step to decouple the FIT image specification from the actual
signing: With these changes, the signature nodes can leave out an algo
property, mkimage will initialize that as well while signing. This way,
in-tree FIT source files can be prepared for gaining signatures without
defining the key type or size upfront, forcing users to patch the code
to change that.

Patch 1 is preparatory for this, patch 2 a drive-by cleanup.

A better solution would actually be if the algorithm was derived from
the provided key. But the underlying crypto layer seems to be rather
unprepared for that.

  image-fit: Make string of algo parameter constant
  mkimage: Drop unused OPT_STRING constant
  mkimage: Allow to specify the signature algorithm on the command line
