I forgot to add. Since the first variant will be on an altera or xilinx
board, the first cut design will use the
DSP blocks on the FPGA. Cores will be the quad core A53 that is found in
the new FPGAs.

We can use our cores in the FPGA variants but soft cores will not be as
fast as the hard cores.
Our SoC development will proceed in parallel.
