Hi Rob,

I'm working on a v2 for this patchset and I've looked on how using "firmware-
name" with the full filename would be possible but as David Summers has already 
written [1], the existing code [2] takes this "postfix" as parameter and 
basically fills it into a filename template ("${CFG_NAME}-${POSTFIX}.bin"). So 
either we stay with the "firmware-postfix" property or the existing code would 
have to be modified to accomodate the full filename; but if using firmware-postfix 
is unacceptable, I can rework the existing code.
