Manufacturing tags

[John Watlington]

As replacing the SPI flash becomes a more regular
occurence, reinstalling the manufacturing tags is becoming
a problem.

What tags are absolutely essential for our software to operate ?

These are:
SN  (serial number)
U#  (uuid)

What about these ?:
LO   (C locale)
KL   (keyboard layout)
LA   (country code)
KA   (Keyboard ASCII map)
KV   (keyboard variant)
WM  (wireless module MAC)
SG  (motherboard rev)
B#   (motherboard number)

As every essential tag must be typed in, with a reboot between
each, I would like to minimize the number of tags I restore.

Cheers,
