What about u-boot?

Building u-boot for the zed board is not difficult the problem is the
convoluted wrapper which requires the XIlinx tools in order to install
it.  I can add directions to the readme.

The basic process is.

source <path/to/xilinx/settings.sh>
cat <<EOF > boot.bif
{
   [bootloader]<path/to/fsbl.elf>
   <path/to/system.bit>
   <path/to/uboot.elf>
}
bootgen -image boot.bif -o i BOOT.BIN

This file then needs to be placed on the SD Card.

Since we're building u-boot, I believe it makes sense to indicate in
the README how to use it. Could you send a followup patch, now that the
initial board support has been merged?

Thanks!
