The physical chip is marked AN7581 but I have seen some old EN7581 uses 
in Airoha(Econet) material. I'm not really happy with this situation but 
for some reason the en7581 name has been pushed for this SoC in mainline 
kernel code.

Ideally linux and uboot should use the same naming but I'm fine with 
whatever gets code landing upstream.
