could you please change the commit subject and message? Your intention
is to make Marek's ag71xx ethernet driver working for AR933x, isn't
it?

If a kernel driver is dependent on the initialization of the
bootloader, then that should be fixed in the kernel driver. The
philosophy of U-Boot is to not initialize hardware at all when it's
not needed by U-Boot itself. Thus if one boots a board without using
network in the bootloader or if one doesn't compile in network
support, the ethernet hardware parts are never initialized. But the
kernel and it's drivers should still work.
