The later is initialized by generic code, so board only needs to opt in to memdev scheme by providing MachineClass::default_ram_id and using MachineState::ram instead of manually initializing RAM memory region. PS: in ref405ep alias RAM into ram_memories[] to avoid re-factoring its user ppc405ep_init(), which would be invasive and out of scope this patch.
