The APM X-C1 (code name Mustang) is a server chip under their X-GENE family of products.
First Look
U-Boot
The board came with U-Boot loaded. When the system is first turned on, you will see the following in the console:

The system comes with their version of Linux installed. It's using a custom version of the 3.12 Linux Kernel. Interestingly, the hostname does not reflect the actual IP address, so most likely it's the IP from a network install from the factory.

Installing Fedora
To install Fedora on the system, we need to get the UEFI loader running first. You can either chainload this from U-Boot by having U-Boot run the UEFI loader from the SD card on start-up, or flash it directly to the system and replace the U-Boot loader altogether.
Chain-Loading UEFI
Since I don't want to replace U-Boot, I will chainload it during startup.
Before you begin, read through the guide on the FedoraProject wiki: https://fedoraproject.org/wiki/Architectures/AArch64/Hardware/Mustang?rd=Architectures/ARM/AArch64/Mustang
Download mustang_uefi_upgrade.tar.gz and dump the contents onto a 2GB FAT16 formatted SD card partition. U-Boot doesn't appear to see the partition if it is any larger than 2GB. Insert the SD card into the X-C1 board and turn it on. Enter the U-Boot shell and run the following:
