Assuming you're going to boot Linux on that board, you will face the
next problem that U-Boot will reset the controller before the kernel
boots and thus vanishes the MAC address from the chip. I sent in another
patch for that which contionally disables this reset so that the Linux
driver can actually read the address again and use it (with the
SMSC911X_SAVE_MAC_ADDRESS flag set). But as Mike Frysinger pointed out,
this is not the intended way to go as the MAC is only programmed if
U-Boot ever performed any network transaction. So there is need for some
other approach, just wanted to let you know.
