Francois, There aren't any ARM device models in the repository currently, so if you do configure a full system ARM assuming you're code does accesses no I/O devices (unlikely) and simply starts executing at the reset vector (0x0), it will probably work. If you want to do this you can look at the other architectures for examples for the changes required to FSConfig.py and pass your binary as the kernel parameter to the fs script. However, if it touches any devices, that won't work for you. I have many changes outstanding to implement better full-system support, however they're simply not done yet.
