Yes, I tested this on a Pine A64-LTS. You can see the difference easily with
md.{b,w,l,q} in the U-Boot shell.

I verified that all three of the following are identical:
 - NVMEM exported to sysfs with the register readout method
 - NVMEM exported to sysfs with this patch series applied
 - SRAM dump made with md.l in the U-Boot shell

Regards,
Samuel
