If this option is enabled, the reg property will be translated
using the fdt_translate_address() function. This is necessary
on some platforms (e.g. MVEBU) using complex "ranges"
properties in many nodes. As this translation is not handled
correctly in the default simple_bus_translate() function.
If this option is not enabled, simple_bus_translate() will be
used for the address translation. This function is faster and
smaller in size than fdt_translate_address()
