Everyone can grab and install Fedora 21-22 on APM Mustang. But what if you want something more enterprise ready? Answer is simple: you can install CentOS 7 (at Alpha stage now).
Requirements are simple:
- APM Mustang (AMD Seattle should be fine as well)
 - USB thumb drive (512MB is enough)
 - network access
 - CentOS 7 Alpha installation iso for AArch64
 - serial cable
 
First fetch iso and then copy to USB thumb drive (simple “dd if=boot.iso of=/dev/sdc bs=4M” is enough). Then just reboot to UEFI shell and run “FS1:EFIBOOTBOOTAA64.EFI” to get into installation.
All files will be read from USB (for Mustang you need official APM firmware 1.1.0 to get proper DTB) and installation goes like with Fedora, RHEL, CentOS — standard Anaconda.
Finally reboot and system is ready for use:
CentOS Linux 7 (Core)
Kernel 4.0.0-1.el7.aarch64 on an aarch64

AArch64 port is now in progress so not all packages are built yet but they will be.
