You are talking about 2 separate things.
The Multiple Address Spaces feature is already in GCC, and two targets support
it. Work is being done on the AVR port right now to support multiple address
spaces, such as __flash and __eeprom.
However, there won't be support for user-defined address spaces which then have
the compiler generate special code to access some other chip X. That should
rightfully be in the user's code, or at the very least, put into a GCC plug-in.
This kind of stuff is very specific to a user or application, and is not
generic enough to warrant inclusion in the compiler itself.
