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.

Currently, mach-apple assumes we're working with M1/M2. Make room for adding support for other Apple SoCs by moving everything from the M1/M2 SoC family in "mach-apple/" into "mach-apple/m1/".
Which other Apple SoCs?
