When customizing omap2plus_defconfig to build for only one board (omap3evm), I came across these warnings and errors (filenames truncated): arch/arm/mach-omap2/board-generic.c:76:20: warning: 'omap4_init' defined but not used arch/arm/mach-omap2/built-in.o: In function `omap2420_init_early': arch/arm/mach-omap2/io.c:364: undefined reference to `omap2_set_globals_242x' arch/arm/mach-omap2/io.c:366: undefined reference to `omap2xxx_voltagedomains_init' arch/arm/mach-omap2/io.c:367: undefined reference to `omap242x_powerdomains_init' arch/arm/mach-omap2/io.c:368: undefined reference to `omap242x_clockdomains_init' arch/arm/mach-omap2/io.c:369: undefined reference to `omap2420_hwmod_init' arch/arm/mach-omap2/built-in.o: In function `omap2430_init_early': arch/arm/mach-omap2/io.c:376: undefined reference to `omap2_set_globals_243x' arch/arm/mach-omap2/io.c:378: undefined reference to `omap2xxx_voltagedomains_init' arch/arm/mach-omap2/io.c:379: undefined reference to `omap243x_powerdomains_init' arch/arm/mach-omap2/io.c:380: undefined reference to `omap243x_clockdomains_init' arch/arm/mach-omap2/io.c:381: undefined reference to `omap2430_hwmod_init' arch/arm/mach-omap2/built-in.o: In function `omap4430_init_early': arch/arm/mach-omap2/io.c:436: undefined reference to `omap2_set_globals_443x' arch/arm/mach-omap2/io.c:438: undefined reference to `omap44xx_voltagedomains_init' arch/arm/mach-omap2/io.c:439: undefined reference to `omap44xx_powerdomains_init' arch/arm/mach-omap2/io.c:440: undefined reference to `omap44xx_clockdomains_init' arch/arm/mach-omap2/io.c:441: undefined reference to `omap44xx_hwmod_init' This patch fixes them. Signed-off-by: Sanjeev Premi <premi@xxxxxx> --- Changes since v1: - #if defined() to #ifdef - Moved an #ifdef to take care of additional warning related to sdp4430_twldata. Had missed squashing the patch before sending v1. Adding ifdefs makes the code bit ugly and is prone to propagate further. Not sure if DT will help here, but this patch would be useful for people trying to build for individual boards. Compile tested for OMAP3EVM.
