You can get the MAC address from related registers of your Ethernet
controller, provided they where set by u-boot. This is way the network
driver goes.
No, you get that from the device tree. You cannot rely on U-Boot to
have initialized the network hardware, or on the network hardware to
not have been reset since then.
