It's internal though.  memory.c users never use it in a way that creates
a RAMBlock.

It's a weird 0-length memory region, and it doesn't have a RAMBlock.
Probably needed only to satisfy ppc405ep_init.

    ram_bases[0] = 0;
    ram_sizes[0] = 0x08000000;
    memory_region_init(&ram_memories[1], NULL, "ef405ep.ram1", 0);
    ram_bases[1] = 0x00000000;
    ram_sizes[1] = 0x00000000;
