The helper function mx31_setup_weimcs() references IOMEM() and IMX_IO_P2V() but without required header mach/hardware.h included in mx31.h. This will break the build of those mx31 based board file with no direct inclusion of mach/hardware.h, or when indirect inclusion to mach/hardware.h breaks. For example, when the inclusion of mach/hardware.h gets removed from mach/gpio.h, we will see the following compile error. CC arch/arm/mach-imx/mach-pcm037_eet.o In file included from arch/arm/mach-imx/devices-imx31.h:9:0, from arch/arm/mach-imx/mach-pcm037_eet.c:20: arch/arm/plat-mxc/include/mach/mx31.h: In function ‘mx31_setup_weimcs’: arch/arm/plat-mxc/include/mach/mx31.h:129:2: error: implicit declaration of function ‘IOMEM’ arch/arm/plat-mxc/include/mach/mx31.h:129:2: error: implicit declaration of function ‘IMX_IO_P2V’ This patch removes mx31_setup_weimcs() from mx31.h and makes it local to mach-qong.c, which is the only user for this helper.
