From 04d2b0c7c2e518c1d44a1347e709af004708dce4 Mon Sep 17 00:00:00 2001 From: Luca Ceresoli Date: Fri, 24 May 2019 15:40:01 +0200 Subject: [PATCH] arm64: zynqmp: xil_io.h: declare functions as static Fixes sparse warnings when building zynqmp defconfigs: ./board/xilinx/zynqmp/xil_io.h:12:6: warning: symbol 'Xil_Out32' was not declared. Should it be static? ./board/xilinx/zynqmp/xil_io.h:17:5: warning: symbol 'Xil_In32' was not declared. Should it be static? ./board/xilinx/zynqmp/xil_io.h:22:6: warning: symbol 'usleep' was not declared. Should it be static? Also add __maybe_unused to usleep() since it is not used by minimized psu_init_gpl.c files, so it would warn as "defined but not used".
