Trying to test this I have hit an error with CONFIG_PHY_ADDR not defined.
I am guessing that I am missing some other sets of patches. digging through
patchwork I am not able to figure it out. there is a bunch of patches in
patchwork that say they are in NEW state however they are in the tree so not
labeled correctly. Any clues as to which patch sets this depends on are
appreciated.

> +Update from original Marvell U-Boot to mainline U-Boot:
> +-------------------------------------------------------
> +
> +Generate the U-Boot image with these commands:
> +
> +$ make clearfog_defconfig
> +$ make
> +
> +The resulting image including the SPL binary with the
> +full DDR setup is "u-boot-spl.kwb".
> +
> +Now all you need to do is copy this image on a SD card.
> +For example with this command:
> +
> +$ sudo dd if=u-boot-spl.kwb of=/dev/sdX bs=512 seek=1
> +
> +Please use the correct device node for your setup instead
> +of "/dev/sdX" here!
