Subject: 32-bit Amlogic SoCs: avoid using Ethernet MAC addresses

I have seen Anand's your question in [0]:

u-boot on the 64-bit SoCs can read the MAC address from the eFuse and
pass it (via the .dtb) to the kernel.
This requires an ethernet0 alias in the mainline .dts though, see [1]
for and example.

I'm not sure if this also works with the older u-boot on the 32-bit SoCs.
if it doesn't then there's a nvmem-cells binding for all Ethernet
controllers: [2] (please note that the function implementing this
binding was recently renamed: [3])
as far as I can tell the stmmac driver doesn't support the nvmem-cells
based binding yet

Anand, if you want to work on this: feel free to do so!
I have the SDHC MMC driver and a discussion about the power-domain
drivers on my TODO-list, so I'm pretty busy at the moment.
