[U-Boot] qemu-system-arm segfaults on zynq_zed

I'm brand new to Uboot, so hopefully this is just some missing switch. I did search the archive, and I was able to build and u-boot a versaatilepb version, but xilinx-zynq-a9 is the one I really need.

u-boot-2014.10$ make zynq_zed_defconfig u-boot-2014.10$ make all CROSS_COMPILE=arm-none-eabi- ARCH=arm u-boot-2014.10$ qemu-system-arm -M xilinx-zynq-a9 -m 1024M -nographic -kernel u-boot-dtb.bin Segmentation fault (core dumped)

What am I doing wrong?
