There are some evolutionary changes of course (updated interrupt controllers and other devices) but they're broadly similar from what I can tell so far. There is also evbppc-powerpc64 (aka evbppc64) and macppc-powerpc64 (aka macppc64). There has been talk (but not much work) about macppc64. Powerpc is (historically) by default big endian, a little endian variant would be powerpcel or powerpc64el. The alias names probably would be evbppc64-el or ofppc64-el. Martin
