The only 64kB range I'm aware of is the optional integration trick to cope with 64kB pages that was documented in the initial SBSA spec. The HW itself only decodes 8kB for the CPU interface. M. -- Without deviation from the norm, progress is not possible. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
