The files ps7_init.c and ps7_init.h are supposed to be generated by hw projects such as Vivado, PlanAhead and then to be copied into board/xilinx/zynq directory.
But some prototypes in them cause annoying warning messages:
CC spl/board/xilinx/zynq/ps7_init.o In file included from board/xilinx/zynq/ps7_init.c:50:0: board/xilinx/zynq/ps7_init.h:137:1: warning: function declaration isn't a prototype [-Wstrict-prototypes] board/xilinx/zynq/ps7_init.h:138:1: warning: function declaration isn't a prototype [-Wstrict-prototypes] board/xilinx/zynq/ps7_init.h:139:1: warning: function declaration isn't a prototype [-Wstrict-prototypes] board/xilinx/zynq/ps7_init.h:145:1: warning: function declaration isn't a prototype [-Wstrict-prototypes] board/xilinx/zynq/ps7_init.c:12602:1: warning: function declaration isn't a prototype [-Wstrict-prototypes] board/xilinx/zynq/ps7_init.c:12723:1: warning: function declaration isn't a prototype [-Wstrict-prototypes] board/xilinx/zynq/ps7_init.c:12742:1: warning: function declaration isn't a prototype [-Wstrict-prototypes] board/xilinx/zynq/ps7_init.c:12761:1: warning: function declaration isn't a prototype [-Wstrict-prototypes] board/xilinx/zynq/ps7_init.c:12854:6: warning: function declaration isn't a prototype [-Wstrict-prototypes]
The prototypes should be
int ps7_init(void); int ps7_post_config(void); int ps7_debug(void);
rather than
int ps7_init(); int ps7_post_config(); int ps7_debug();
We do not want to be bothered because of automatically generated files. But we cannot touch the external projects for now. What we can do is to disable -Wstrict-prototypes for ps7_init.c
