arm64: zynqmp: add tool to convert PMU config object .c to binary The recently-added ZYNQMP_SPL_PM_CFG_OBJ_FILE option allows SPL to load a PMUFW configuration object from a binary blob. However the configuration object is produced by Xilinx proprietary tools as a C source file and no tool exists to easily convert it to a binary blob in an embedded Linux build system for U-Boot to use. Add a simple Python script to do the conversion. It is definitely not a complete C language parser, but it is enough to parse the known patterns generated by Xilinx tools, including: - defines - literal integers, optionally with a 'U' suffix - bitwise OR between them Signed-off-by: Luca Ceresoli <luca@lucaceresoli.net> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
