I am working a new device which is based on ipq806x, and has NAND flash with a UBI (kernel + rootfs + ubifs).

This device uses Qualcomm's SMEM partition table in flash, which regrettably defines our UBI partition as being named "rootfs".

The mtd-qcom-smem-rename-rootfs-ubi.patch is apparently supposed to rename any partition named "rootfs" to "ubi", but that doesn't appear to be working for me.

The result is that automatic mounting of the UBI and real rootfs fails. I have worked around this by defining kernel arguments in my DTS file.

While we are at it, my system has a redundant UBI partition named "rootfs_1". It would be nice to rename it to "ubi_1".
