Package: linux-image-4.17.0-1-powerpc64le Version: 4.17.8-1 The MTD partitions of the main firmware Flash device are not exposed as MTD device nodes on PowerNV systems. This makes firmware updates difficult, requiring manual intervention on the loader shell.
This issue has been fixed upstream via a one-line kernel patch (attached, see also [1]). Debian kernels should include this patch to allow firmware updates to be applied to PowerNV machines. Thank you! [1] https://patchwork.ozlabs.org/patch/943327/
