Assume we have a 1GB(8Gb) nand chip:
  #gpmi-nand:1g@...m(rootfs),100m@0(boot),100m@...m(kernel)

I am used to explicitly specify size@...set for all my parts.

Obviously I won't define a partition above the device size... somewhat
hypothetical discussion here...

But your code will stop after creating 'rootfs' (and original code will
not create a single partition).

Is that what we want?

Or do we want to truncate 'rootfs', but still have the valid 'boot' and
'kerner' partitions?
