As the message indicates, the update script fails to find a mtd partition for
"image-bmc".
What is your devices's mtd parts?
The expected OpenBMC flash layout is like this:

# ls -l /dev/mtd/
total 0
lrwxrwxrwx    1 root     root             7 May 30 06:47 bmc -> ../mtd0
lrwxrwxrwx    1 root     root             7 May 30 06:47 kernel -> ../mtd3
lrwxrwxrwx    1 root     root             7 May 30 06:47 pnor -> ../mtd6
lrwxrwxrwx    1 root     root             7 May 30 06:47 rofs -> ../mtd4
lrwxrwxrwx    1 root     root             7 May 30 06:47 rwfs -> ../mtd5
lrwxrwxrwx    1 root     root             7 May 30 06:47 u-boot -> ../mtd1
lrwxrwxrwx    1 root     root             7 May 30 06:47 u-boot-env -> ../mtd2

For "image-bmc" it will update the partition labeled "bmc", which is mtd0.
