That's cool.

If the question is just about hexdump, then hexdump itself can read file 
from given offset and size.

But I believe the real question is "How can we dump each nvmem cell 
independently"

In one of my replies I mentioned that am planning to add sysfs entries 
under /sys/class/nvmem/<provider>/cells/

ex:
for qfprom tsens calibration it would look like:

$ hexdump /sys/class/nvmem/qfprom0/cells/tsens_calibration

0000000 e000 0c00 0c00 0000 0c00
...

Is that what you guys are looking for?
