From: Rob Herring <[email protected]> SWIG cannot generate setters for a struct's flexible array member and emits C that does not compile:
./pylibfdt/libfdt_wrap.c: In function '_wrap_fdt_node_header_name_set': ./pylibfdt/libfdt_wrap.c:4350:18: error: cast specifies array type ./pylibfdt/libfdt_wrap.c:4350:16: error: invalid use of flexible array member ./pylibfdt/libfdt_wrap.c:4613:18: error: cast specifies array type ./pylibfdt/libfdt_wrap.c:4613:16: error: invalid use of flexible array member Turns out this is a known issue with SWIG: https://github.com/swig/swig/issues/1699 Implement the work-around to ignore the flexible array member. U-Boot's copy of fdt.h still declares those members as zero-length arrays, so nothing breaks today, but carrying the work-around now keeps the shipped file in step with upstream and avoids the failure when the C libfdt is next resynced. This is a backport of dtc commit abbd523bae6e ("pylibfdt: Work-around SWIG limitations with flexible arrays").
