[U-Boot] ARM: Running U-boot on Raspberry Pi Zero W

Hi
We are trying to run U-Boot on the Raspberry Pi Zero W. But all our attempts have finished at rainbow screen. During our experiments we have been following an instructions from (with a different config file, configs/rpi_defconfig).
http://ltekieli.com/buildroot-with-raspberry-pi-u-boot/
Also we have tried a method from
http://www.embeddedforu.com/embedded-linux/raspberry-pi/how-to-compile-mainl...
However we have got the same result in both cases. At the same time we don't have any problem with Raspbery Pi 3 (with a different config file configs/rpi_3_32b_defconfig).
We are using buildroot 2017.05 which contains U-boot 2017.03.
Thanks in advance,
