From 747c4c68c042babb2179b52b60bc78611e3e1183 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 1 Jul 2017 11:06:09 -0600 Subject: stm32: Correct positioning of declaration The current code gives a warning: arch/arm/mach-stm32/stm32f7/soc.c: In function 'arch_cpu_init': arch/arm/mach-stm32/stm32f7/soc.c:38:2: error: 'for' loop initial declarations are only allowed in C99 or C11 mode for (int i = 0; i < ARRAY_SIZE(stm32_region_config); i++) ^ arch/arm/mach-stm32/stm32f7/soc.c:38:2: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 to compile your code Fix it by moving the declaration to the top of the function.
