Okay, I've done that by copying the relevant dts sections from
sun4i-a10-cubieboard.dts. It initialises and transmits packets fine. But
it doesn't seem to accept incoming packets. I suspect that programming
of its own MAC address (which the driver chooses randomly) suffers from
an endianness issue. I'm somewhat stumped as to what is causing it since
all accesses use {read,write}l. Interrupt handling is another possible
culprit. I'm still digging.
