This way the initcalls don't run on other SoCs on multiplatform kernels. Otherwise we'll get something like this when booting on vexpress: omap_hwmod: _ensure_mpu_hwmod_is_setup: MPU initiator hwmod mpu not yet registered ... WARNING: at arch/arm/mach-omap2/pm.c:82 _init_omap_device+0x74/0x94() _init_omap_device: could not find omap_hwmod for mpu ... omap-dma-engine omap-dma-engine: OMAP DMA engine driver ... Tested-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
