Actually, looking into u-boot_2016.03 (this is this uboot version in morty by default right ?) it seems the zynq_zybo.h is different.
http://git.denx.de/?p=u-boot.git;a=blob;f=include/configs/zynq_zybo.h;h=0882fe36bd82ef68b9515c0c265fc4015d673496;hb=df61a74e6845ec9bdcdd48d2aff5e9c2c6debeaa

And the commit in poky for u-boot point to this revision df61a74e6845ec9bdcdd48d2aff5e9c2c6debeaa.
So I need to upgrade the revision I guess. 
Maybe the best things to do is to upgrade my build from morty to pyro . It uses the new u-boot version 2017.01.
I'll try it I think.
