xilinx 7-series tools

WARNING: very poor code quality. expect that you'll probably have to make changes to fit your needs

• xilbitstream.py - a script that prints the contents of 7-series bitstreams and saves files for any configuration frames found inside. supports either endian, with or without the xilinx header. nominally does not crash on encrypted bitstreams (!!), but of course it can't really make any sense of them either - you'll need the key
• xilswap.py - simply swaps endianness of each 32 bit word. nothing too fancy
• pcap_dump_tool - a bare metal ARM tool for zynq bitstream readback. it saves the currently loaded bitstream to emmc. it's bare metal because the xilinx linux driver had a bug that prevented it from working correctly. additionally, some low-level steps needed to be taken to ensure the readback was not corrupted. comments explain each step. you will need to adjust the parameters based on the fpga part you have, however. also it needs to be built with the xilinx toolchain
