[OpenRISC] FPU licensing request

[OpenRISC] FPU licensing request

[Julius Baxter]

Hi Jidan,

I'm getting in touch because I want to ask your permission to
relicense some of your FPU code.

I ported your VHDL FPU design to Verilog many years ago (2010 I think)
and it's since been included in the mor1kx OpenRISC CPU project by
Andrey Bacherov (CC'ed).

Example: https://github.com/openrisc/mor1kx/blob/master/rtl/verilog/pfpu32/pfpu32_addsub.v

It's currently got what looks like a permissive licence (as you can
see in the link above) but I would like to ask if we can relicense the
code under the CERN OHL V2 weakly permissive licence.

In summary, this licence is a file-level copyright for hardware
designs. The FAQ on CERN's site about the OHL is great for explaning
what the OHL v2 is what the W variant means:
https://ohwr.org/project/cernohl/wikis/faq#q-what-are-all-these-suffixes

This would only apply to this copy of the source. It does not affect
the other copies which are out there on the internet. I only ask this
for consistency across the mor1kx CPU project.

Your permission to do this would be greatly appreciated.

Happy to answer any other questions you have.

Cheers,
Julius

Correction: relicense the code under the CERN OHL v2 weakly
_reciprocal_ licence.

Hi Julius,

I don't think you need my permission for this, but thanks anyway for
asking. Please do as you wish.
It's amazing how >10 years pass so fast...

Wish you all the best and take care!
Jidan

That's appreciated Jidan, thanks very much.

Agreed, time flies huh?

Cheers,

Hello All.

1) All mor1kx contributors agreed with the license changing.
2) MAROCCHINO is complete rewrite of CAPPUCCINO

As I understand correctly there isn't an objection to changing the 
license for MAROCCHINO sources. Am I right? I'm going to do this if so.

WBR,
Andrey
