It would be good if ICube released their VHDL to show their intentions
are made of gold.

Open Cores have done it http://opencores.org/shop,items

Their OpenRISC processor SoC runs Linux.

[I bought their FPGA board to run the VHDL - but was not smart enough
to spot I needed the USB JTAG debugger to go with it so I can't comment
yet about the power of that SoC.]

It seems to me they got everything there needed including huge amounts
of open sourced IP needed to build SoCs. (They did
a failed kickstarter project, but still their boards got made and
nearly always they are out of stock these days.)

For sure, this CPU is not an arm, and so its not encumbered with
ARM IP; which makes it a lot easier to adapt and expand.

Also the software headers I was talking about earlier can be
more easily managed because you would be starting out with
a new CPU and not fighting the sea of 20 billion+ ARM chips
out there without header files and names for register and bit fields.
