51xx would be confusing because 5100 was a precursor to the 5200.
Adding it to 52xx would is wrong because 5121 is really not that
much like a 5200. It is really a 83xx minus some networking hw
plus some 5200 peripherals (PSCs and MSCAN).
In the best of possible worlds it would have a 83xx part number
and go in 83xx but that would be confusing since it is targeted
at the automotive market.
