I'd say ram_addr_t is an appropriate type.
Currently this is defined in cpu-defs.h. It should probably be moved elsewhere
because in the current implementation it's really a host type.
If we ever implement >2G ram on a 32-bit host this may need some rethinking.
We can deal with that if/when it happens though. Requiring a 64-bit host for
large quantities of ram seems an acceptable limitation (N.B. I'm only talking
about ram size, not target physical address size).
