explain how [pi400]/[cm4] conditional filters interact with [pi4]

[clockfort]

see raspberrypi/firmware#1496 (comment) for citation/background; the current behaviour is poorly documented.

Sorry for making the table a little ugly though. I would have made this note a footnote instead, but I don't know what flavours of extended markdown will work with your guys' html documentation generator, etc.

Thanks!

This might be better as a footnote rather than inline. Also the reference should be for Pi 400 and CM4 - note capitalisation.

reworded and made the requested changes

I'm going to be freezing the current Markdown-based repo for PRs on Monday morning, see #1911 for details of what's going on. If this PR isn't merged before then it will unfortunately be deleted. Although we'll be happy to get a new PR against the new Asciidoc-based repo after that goes public — which will probably at the start of August.

Ah, no worries, thanks for the explanation. Good luck with your migration, I'll see you in a month I guess if no one merges this over the weekend.

LGTM so merged before the deadline!

Doesn't really matter now, but perhaps this should have been added to the "It is important to note that the Raspberry Pi Zero W will see the contents of [pi0w] AND [pi0]. Likewise, a Raspberry Pi 3B Plus sees [pi3+] AND [pi3]. If you want a setting to apply only to Pi Zero or Pi 3B you need to follow it (order is important) with a setting in the [pi0w] or [pi3+] section that reverts it." paragraph?

I agree. I just didn't see that paragraph as it didn't match the newer keywords I was searching for.

@clockfort What do you think to #1943 ?
