Patch 3 - 7 have previously been discussed on the mailing list, patch
1 and 2 have been reviewed by Rob, patch 8 ("mtd: ubi: provide NVMEM
layer over UBI volumes") still needs review.
Is there anything I can do from my end to have this series moving
forward?
Patchwork: https://patchwork.ozlabs.org/project/linux-mtd/list/?series=368347
Thank you for your advise!

Richard. I guess the queue of UBI pending patches is at:
