I'm currently working on S5L8950X. I also have some T7000 and T8010
devices that I'll work on in the future.
There's a project called freemyipod that has a fork of U-Boot working on
iPod Nano's (specifically the S5L8730 in the iPod Nano 5). I've read
that they're planning on upstreaming it in the near future.
