> The iMX515 targets the same automotive markets as the MPC5xxx lines did

While it is true that there are i.MX processors which are about to substitute certain MPC5xxx regarding automotive, your claim has several flaws:

1. The MPC55xx/56xx (automotive: engine management and driver assistance) are not supposed to be substituted by any i.MX. It's only the MPC51xx/52xx (automotive infotainment) your claim fits.
2. Freescale don't target the i.MX515 at automotive at all, but at consumer market (netbooks, nettops).
3. The only i.MX processors targeted at automotive are some i.MX25/31/35. There they serve infotainment purposes only (like the MPC51xx/52xx regarding automotive).
