Yeah, great idea! As far as I can see last time it was updated in 2013! More than 10 years ago...

But having a table of supported hardware is really handy. I think it makes sense to spend time on finding any built-in methods in sphinx that can help us maintain a table in this document instead of the wiki.

File doc/supported_hw/supported_flashchips.rst:

PS2, Line 12: Alternatively inspect the file on the `web UI of our GitHub mirror https://github.com/flashrom/flashrom/blob/main/flashchips.c`_.
I would suggest moving this paragraph to the first one, because they're logically related

PS2, Line 14: If you want to check whether a flash chip is supported in the given release, you can rebase your local
            : repo at the release tag, alternatively select a tag/branch in GitHub web UI (dropdown on the top-left).
It doesn't sound like a really user-friendly method to check whether a desired flash chip is supported :(

Can we maintain a list of supported chips for a specific release as a text file? Looks like we have to add it to the upcoming agenda :D

How about just adding them as a "related topics" list?
