I found how to fix the problem. 

Add one line to arch/arm/cpu/armv7/zynq/u-boot.lds as follows:


  --- a/arch/arm/cpu/armv7/zynq/u-boot.lds
 +++ b/arch/arm/cpu/armv7/zynq/u-boot.lds
 @@ -18,6 +18,7 @@ SECTIONS
         .text :
         {
                 *(.__image_copy_start)
 +               *(.vectors)
                 CPUDIR/start.o (.text*)
                 *(.text*)
         }


It  worked on my ZC706 board.
