Hi, Zev,

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).

Reply by Kelly:
I will correct the label with "bmc" and use 64M patition then update in v3 patch.

Reply by Kelly:
I also remove bios partition section and rename label with "bios".


Thanks for review.

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.
