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

[Douglas Rupp]

The result is:

arm-softmmu/qemu-system-arm -M arm-generic-fdt -nographic -smp 2 -machine
linux=on -serial mon:stdio -dtb devicetree.dtb -kernel boot.bin
SPI device 0x7f8161521ee0
qemu: fatal: Trying to execute code outside RAM or ROM at 0xfffffff0

then a register dump

The "boot.bin" and "devicetree.dtb" is from xilinx binary release
2014.3-release/zed

I tried removing -smp 2 -machine linux=on, and same error.
