Floating point in 8260

[Neil Russell]

As I understand it, there is no production 8260 without an FPU.  Current
production chips are rev A.1 which have an FPU, and new production are rev B
which will also have an FPU.  You probably have no choice for production, so
you should upgrade your test board if it has old an CPU.
