Adding hardware licenses to Non-Software Licenses

[nytpu]

Adding an open hardware license section to the Non-Software licenses page is very beneficial, especially since there seems to be a lot of outdated and fragmented information about them on google.

It looks like bigger open hardware companies like Adafruit and Sparkfun use the CC BY-SA for most of their stuff, but I think the CERN OHL v2 family of licenses should also be included as they cover aspects more common with hardware like patents and such as well as just copyright.

The CERN OHL v2 is a family of licenses, with a permissive version (MIT-like), weakly reciprocal version (MPL/LGPL-like), and a strongly reciprocal version (GPL-like). The set of licenses mostly fits the “Adding a License” critera, each has an SPDX identifier: CERN-OHL-P-2.0, CERN-OHL-W-2.0, CERN-OHL-S-2.0; and each is approved by the OSI: https://opensource.org/CERN-OHL-P, https://opensource.org/CERN-OHL-W, https://opensource.org/CERN-OHL-S. However, while all three licenses have 1,561 projects on github plus at least 380 projects off of github (19 pages x 20 entries per page), each individual license has less than 1,000 projects, technically not meeting the criteria. I personally believe it merits inclusion—it's certainly not an obscure license, and the main goal of the inclusion criteria seems to be to weed out non-notable licenses—but I'd like to have explicit approval before adding it.

I'll make a pull request adding the CERN OHL and the hardware section to the non-software page, but I wanted to get a go-ahead that it's okay to add the CERN OHL first. Even if the CERN OHL isn't okay to be added I'll make a pull request to add the CC BY-SA to a hardware section.

Those searches are overly inclusive, they obviously include a lot of non-CERN-OHL-* materials. Here are searches probably unique to each license, for github.com anyway:

• https://github.com/search?q=%22this+CERN-OHL-P%22+filename%3ALICENSE&type=Code (162 results)
• https://github.com/search?q=%22this+CERN-OHL-W%22+filename%3ALICENSE&type=Code (77)
• https://github.com/search?q=%22this+CERN-OHL-S%22+filename%3ALICENSE&type=Code (216)

each individual license has less than 1,000 projects, technically not meeting the criteria

This is the fuzziest criteria. I'd welcome a PR that adds all 3 (I think it'd make sense to do as a a group to ensure consistency), which includes finding 3 solid examples for each. I don't promise to merge immediately but if you're willing to be patient, it'd be useful. Thanks for opening this.
