The officially described way to generate boot.bin files for ZynqMP is to describe the contents of the target binary using a file of the "bif" format. This file then links to other files that all get packed into a bootable image. This patch adds support to read such a .bif file and generate a respective ZynqMP boot.bin file that can include the normal image and pmu files, but also supports image partitions now. This makes it a handy replacement for the proprietary "bootgen" utility that is currently used to generate boot.bin files with FSBL.
