There are no timeframes. Rockbox is entirely volunteer effort, so the best possible answer is "we'll add it to the supported list on the front page when it's supported."
As for status, please search. There's a ton of information about what is and is not working, and rather than having people ask all the time we ask that they read the actual thread on it. We've even got guidelines that new ports should happen in a single thread so that it's easy to find.
