DESCRIPTION="
ARM v4, with thumb support, little endian, EABI, soft float.

This is the lowest-end arm instruction set that can support EABI, the current
binary ABI documented by ARM.  It's used used in 920t processors (such as the
OpenMoko Freerunner).

This is \"the i386 of ARM\", an extremely generic low-end arm image that
should run on any arm hardware still in use today (except ARMv7M, which
is arm in name only).
