Well, this appeared when working on the !MMU stuff. Because on the MMU SoC, CLKSRC_OF is selected by ARCH_MULTIPLATFORM and CLKSRC_MMIO is selected by ARCH_MXC, it would not be a problem for MMU SOC_VF610. But I guess we should try to define dependencies on the lowest level, so it is probably a general fix? -- Stefan
