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
