Update uboot from 2016.05 (no replies)

A list of only 6 checked items, that is what I need to do:

☐ Check /etc/fw_env.config and /proc/mtd
☐ Set ethaddr
☑ Dump NAND mtd0 and Save envs
☑ No bad block
────────────
☑ Extract the archive
☑ Erase mtd0
☑ Write image to NAND
────────────
☐ Flashing default u-boot envs image
────────────
☑ Double check uBoot envs 
☐ Set up netconsole

I think I can skip the task of flashing default envs image, below is a diff of my current envs and the uboot.2016.05-tld-1.environment
