Fedora ARM Remixes
Some ARM devices are not officially supported by Fedora because of proprietary drivers and firmware that do not meet the Fedora guidelines. Below includes a list of devices and links to unsupported Fedora Remixes.
The Raspberry Pi is supported by work done at Seneca College in Toronto, Canada. You can find more information by visiting their site, including links to current release images
Creating your own Remix
Anybody can create a remix of Fedora 18 for their ARM device. Generally all that is needed is an appropriate kernel for the hardware in question. See Architectures/ARM/Installer for an introduction into building images based on a kickstart file.
