As with other platforms vendors love to create their own boot header formats. Xilinx is no different and for the Zynq platform/SoC there exists the "boot.bin" which is read by the platforms bootrom. This format is described to a useful extent within the Xilinx Zynq TRM. This implementation adds support for the 'zynqimage' to mkimage. The implementation only considers the most common boot header which is un-encrypted and packed directly after the boot header itself (no XIP, etc.). However this implementation does take into consideration the other fields of the header for image dumping use cases (vector table and register initialization).
