FWIW I have no insight into that effort, but to reiterate, if the secure
side rejects the image, that's not related to what's using it (i.e. if
there's anything wrong with the driver support, that's totally a separate
issue that you may only hit after the fw loader is made happy).

There have been recent changes to the fw loading scaffolding (introducing
an alternative backend to scm), so I'm not ruling out something went wrong
there. But that would break loading on *all* devices, not just production
ones. Unless there's some memory corruption somewhere that makes the
checksums not right..

FWIW I'm running linux-next/master + a couple of unrelated-to-fw-loading
patches on another production machine (glymur-based) and the various
firmwares (incl. for Iris) load just fine
