No this is unrelated. The MAC isn't configured by the boot loader when
the NIC is not used. U-boot only passes it as a non-standard ATAG. I
have some patches to reinject the non-standard atags into the device
tree if you absolutely need this, but they're not suited for mainline
inclusion from what I understood last time I proposed them (they use
a marvell-specific atag header).

Regards,
Willy
