Is this specific label needed or desired for some particular reason?
Most OpenBMC platforms just call it "bmc", and I think some of the
firmware-update machinery may have assumptions about that baked in, so I
wouldn't be surprised if this naming breaks things...

Just to confirm, this is actually a 128MB flash chip?  I ask because the
previous version of this patch had some indication of it being 64MB
(though there was a lot that looked wonky with the partition layout, so
maybe that was wrong too).

If there's only one partition that's just covering the whole chip
there's no need to include the 'partitions' child node.
