This is because we don't have place to put U-Boot environment
variables as of now on Unleashed board. This will be solved once
we have SPI driver and SPI_MMC driver for Unleased board.

In future, we will be saving "ethaddr" environment variable on
SPI_MMC so U-Boot will pick MAC address at boot-time from
SPI_MMC. Once this is achieved, the above warning will go away.
