I just stumbled across this commit since I had an issue with crypto@40900000 not being probed on Verdin AM62. Not sure how this is supposed to work about backward/forward compatibility, however this is needed for having it working with the latest firmware. And if there is a proper way that take care of this, it should be backported IMO. Francesco
