* The EP80219 and IQ31244 use the same machine ID. To find out

* Until March of 2007 iq31244 platforms and ep80219 platforms shared the
* same machine id, and the processor type was used to select board type.
* However this assumption breaks for an iq80219 board which is an iop219
* processor on an iq31244 board. The force_ep80219 flag has been added
* for old boot loaders using the iq31244 machine id for an ep80219 platform.
