Hi Paul,
sorry for late answer - I read only now you are talking about FIT.

Indeed. This is what I did in a couple of projects. I added an
image_types_itb.bbclass to produce the FIT image. The IMAGE_FIT_ITS
variable contains the filename of the description file to be passed to
the mkimage tool, and can be overwritten by the image receipe.
Compressions are not needed for this image type, and I should be removed.
Is this the right place to post the patch ? Or should be addressed to
meta-oe ?
Best regards,
Stefano
