For ZynqMP you likely got it from UG1137? This makes it easy for others to refer back to the documentation, as well as for legal reasons so that it is clear the details come from the user guide and not the FSBL source. Since for Zynq the FSBL specific image/partition table headers were only documented by Xilinx in the FSBL source itself, which is licensed such that it is incompatible with GPL.

The zynqmp image format has support for inline partitions which are used by FSBL to describe payloads that are loaded by FSBL itself. While we can't create images that contain partitions (yet), we should still at least be able to examine them and show the user what's inside when we analyze an image created by bootgen.
