[U-Boot] [PATCH v4 2/2] arm64: zynqmp: add tool to convert PMU config object .c to binary

Wed May 15 08:56:19 UTC 2019
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

Changes v3 -> v4:
- move to tools/ directory
- remove double item.strip() call
