I have not documented anything about linux-imx-rt in #RN 1) because I don't really know it 2) because it's not a default kernel for any board, so the script does not "find" it when looking for the "default linux kernel providers" However, being a community effort makes it even more important to be documented. I would suggest for the first draft, include the kernel description and a small section with some more information such as external links and what to expect. What do you think? Would you mind to help me on that?
