This enables the RSA algorithm used for FIT image What iMX families does this work on? I think we need to look at fixing the logic to be a bit more restrictive to start with, instead of opting families out.

Investigating all imx families and reworking everything around would take much more time and can't be done right now. Anyway, thanks for your question, I rechecked the patch and improved it.
