If no SoC is selected, we should build in only minimal code to bring up a new SoC as none of the SoC specific features are implemented. Otherwise we will get multiple randconfig errors when no SoC is selected. Fix this by tagging the SoC dependant code with soc-y in the omap2+ related makefiles as suggested by Arnd Bergmann <arnd@xxxxxxxx>. Note that we could improve some of the dependencies further by adding a silent Kconfig entry for SOC_OMAP. But let's do that separately as that's not needed for the minimal fix. Without this patch the build errors are something like: arch/arm/mach-omap2/built-in.o: In function `_add_initiator_dep': arch/arm/mach-omap2/omap_hwmod.c:691: undefined reference to
