DESCRIPTION="
ARM v4, little endian, soft float, OABI.

This is a generic low-end arm image that should run on any arm hardware
still in use today (except ARMv7M, which is arm in name only).

The downside is it uses the Old Application Binary Interface, described here:
http://www.linuxfordevices.com/c/a/Linux-For-Devices-Articles/Why-ARMs-EABI-matters/

This instruction set cannot support EABI, which requies the Thumb extensions.
It's sort of the 80286 of the ARM world.
