But this is conceptually broken.  The IH_TYPE_* definitions are
actually only relevant for legacy images.

FIX images use an XML based, extendable data format.  The whole idea
of this is that we do NOT have to change to code when anybody needs a
new (probably private) entry or type or whatever.

In your case, it should be possible to use an existing image type
(say, IH_TYPE_FIRMWARE) for your code, and use other distinguishing
marks to determine which parts you work on.  Probably it makes sense
to define your own entry for each of the parts.  Then only your own
code needs to understand this.

Thanks.

Best regards,

Wolfgang Denk
