Current versions of u-boot use the memory size which is provided by device trees now (for zynq), so make sure you update the value in your u-boot device tree. (you can used 'reserved-memory' for the 16MB FPGA segment) Also it is additionally worth noting to make sure "fdt_high" is set in your environment such that you can load at 0x0200_0000 or above (the default is normally set to 0x2000_0000).
