At present we decode simple bus <ranges> using the following assumption: - parent #address-cells 1 - child #address-cells 1 - child #size-cells 1 However this might not always be the case. Update to use fdt_addr_t and fdt_size_t in 'struct simple_bus_plat', and use fdt_read_ranges() to correctly decode it according to the actual parent and child #address-cells / #size-cells under a Kconfig option CONFIG_SIMPLE_BUS_CORRECT_RANGE which can be turned on for any board that needs it.
