the uboot of nsa310 cannot use the network chip
as it is a realtek on the PCIe lanes and not a
Marvell ethernet from the SoC.
Therefore tftp is not possible on this device
and the only way to install is by loading files
from a USB drive.
If the USB subsystem is dead there is no way to
install OpenWrt.
Enable sata support and commands so it can be
used as a fallback in case of USB issues.
