See the Porting guide
http://ecos.sourceware.org/docs-latest/ref/hal-porting-guide.html
You should only need to do a HAL varient port since the PowerPC is
will supported. You might also need to write a serial device driver,
ethernet driver, watchdog, hardware dependent flash driver etc, it all
depends on your hardware and how much it is like some other device
which eCos supports.
