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
