R8A7792 SoC doesn't have the EtherMAC core, so SMSC LAN89218 Ethernet chip was used instead on the Blanche board; this chip is compatible with SMSC LAN9115 for which there's a (device tree aware) driver. Describe the chip in the Blanche device tree; enable DHCP and NFS root in the kernel command line for the kernel booting.
