The Fedora ARM team has been doing a great job at testing and seeing a wide-range of ARM development boards and other consumer devices will work with the upcoming Fedora 21 release.

Fedora 21 by default is likely shipping with the Linux 3.16 kernel and thankfully there's good ARM support there with a number of improvements having landed into the now-stable kernel. Peter Robinson who specializes in Fedora on ARM shared the "primary" devices they wish to support with Fedora 21:

- Wandboard (all models/revisions)
- Utilite (all models)
- Cubox-i (all models)
- Hummingboard
- RIoTBoard
- BeagleBone Black
- Tegra K1 Jetson
- CubieBoard (all models)
- Banana Pi
- Trimslice
- PandaBoard (all models)
- Calxeda Highbank/Midway
- VExpress (qemu)

Everything from the high-end Jetson TK1 to older platforms like the PandaBoard. When it comes to ARM64/AArch64, the AMD Seattle server platform will be supported, the APM Mustang rference platform, and the VExpress QEMU model. There's also a whole slew of "secondary" ARM devices for Fedora 21 as listed on Peter's blog.
