It's a pretty old chip, and there's a newer generation of Freescale stuff -- the e6500 -- with more cores, smt, pcie 3, etc. Plus, it's kinda expensive compared to other PPC boards. Even the Qoriq reference board is cheaper [1], and reference boards tend to be rather high priced themselves. If you're gonna run Linux, your best bet is elsewhere.
