This script transforms a pair of psu_init_gpl.c and .h files produced by the Xilinx Vivado tool for ZynqMP into a smaller psu_init_gpl.c file that is almost checkpatch compliant.
Based on a script by Michal Simek.
Signed-off-by: Luca Ceresoli luca@lucaceresoli.net
Changes v1 -> v2:
- document that is INPUT_DIR==OUTPUT_DIR then psu_init_gpl.c is overwritten
- minor improvement to commit message
- show help text if script is called without parameters (Michal)
