tools: zynqmpimage: Add Xilinx ZynqMP boot header generation
Add support for the zynqmpimage to mkimage. Only basic functionality is supported without encryption and register initialization with one partition which is filled by U-Boot SPL. For more detail information look at Xilinx ZynqMP TRM. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Reviewed-by: Simon Glass <sjg@chromium.org>
