Yes, it seems like something else must be going on as well as
"usbethaddr" which U-Boot will populate with a MAC based on the OMAP DIE
ID doesn't get populated into the DT only ethaddr.  And the follow-up is
that it would be nice if someone would go and patch the last driver in
U-Boot that uses usbethaddr to use ethaddr like all of the rest do.
