Uboot is installed in a wrapper file called BOOT.BIN located on the root of
the SD card. To create the BOOT.BIN file do the following.
source <path/to/xilinx/settings.sh>
cat <<EOF > boot.bif
{
[bootloader]<path/to/fsbl.elf>
<path/to/system.bit>
<path/to/uboot.elf>
}
EOF
bootgen -image boot.bif -o i BOOT.BIN
