Documentation for new CPUs or MCUs are happily accepted. It's preferred to add processor family architecture documents.
The GitHub 1G size limit on repositories is a concern. If a subdirectory grows large, please add it as a git submodule. The submodule repository should belong to the awesome-cpus origanization. Everyone are welcome to join.
Please limit the scope of each commit to one subdirectory, and make the first line of the message describe the CPU family.
