Baruch Siach	6cb971114f	xtensa: remap io area defined in device tree ... Use the simple-bus node to discover the io area, and remap the cached and bypass io ranges. The parent-bus-address value of the first triplet in the "ranges" property is used. This value is rounded down to the nearest 256MB boundary. The length of the io area is fixed at 256MB; the "ranges" property length value is ignored. Other limitations: (1) only the first simple-bus node is considered, and (2) only the first triplet of the "ranges" property is considered. See ePAPR 1.1 §6.5 for the simple-bus node description, and §2.3.8 for the "ranges" property description.
