mainline u-boot support is using configuration based on dts files (OF_CONTROL)
And because our DTSes are almost empty in mainline I expect you are not able
to see anything from u-boot.
I recommend you to copy dts file from xilinx kernel and then use u-boot-dtb version.
Or the second option is to remove OF_CONTROL from zynq-common.h file
and then I hope you should be able to see something on console.

Thanks,
Michal
