I'm not completely up-to-speed on open source / patent free processors.
>From a few mins reading I came up with this:
- OpenRISC: from scratch RISC. Not in mainline kernel. Can one buy a chip
- RISC-V (lowrisc): UCB made it freely available but no chip yet and not in
- Super-H (sh2 and sh4): Slower than the others (maybe not sh4-64?). Kernel
has support. sh2 is now patent free, sh4 should be patent free this year or
I'm taking a wild guess that the above is woefully inaccurate?
