I think this violates U-boot policy of only touching
hardware if it's
used, but Wolfgang can say for sure. In general, initialize() functions should just set up data structures and register
the device.
There's a long history of MAC-address issues with ARM chips

that I've happily stayed clear of so can't claim to be an
expert here.
OK, I've tried looking around at how other boards do it, and at least the most similar (mv6436x_eth_initialize() for other
This is a wrong reference, even this was my initial reference, but there are no updates to this code, we were planning to clean it but we do not have hardware to test it. Does any one have it?
Marvell boards) do it the same way as well as some others (ax88180.c).
