Are these patches online somewhere? That sounds interesting. I guess I can get rid of ARCH_MXCM4 then. Still, SOC_VF610M4 will be needed. We just need to make ARCH_MXC also available on !MMU and use if to distinguish !MMU/MMU SoC's. -- Stefan -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
