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.

You need to add <asm/global_data.h> here too.
