Hello Hung-Te Lin, Patrick Georgi,
I'd like you to do a code review. Please visit
https://review.coreboot.org/c/coreboot/+/34919
to review the following change.
Change subject: Remove MIPS architecture ......................................................................
Remove MIPS architecture
The MIPS architecture port has been added 5+ years ago in order to support a Chrome OS project that ended up going nowhere. No other board has used it since and nobody is still willing or has the expertise and hardware to maintain it. We have decided that it has become too much of a mainenance burden and the chance of anyone ever reviving it seems too slim at this point. This patch eliminates all MIPS code, MIPS-speicfic hacks and any board and SoC code depending on it.

Change subject: Remove MIPS architecture ......................................................................
Remove MIPS architecture
The MIPS architecture port has been added 5+ years ago in order to support a Chrome OS project that ended up going nowhere. No other board has used it since and nobody is still willing or has the expertise and hardware to maintain it. We have decided that it has become too much of a mainenance burden and the chance of anyone ever reviving it seems too slim at this point. This patch eliminates all MIPS code, MIPS-specific hacks and any board and SoC code depending on it.

If we remove this before the next release, we should go back to the 4.10 release notes and mark it as removed there so it's easier for people to find.
I'm confused... isn't 4.10 done? Why would we put it there? I thought the notes for every release tally up what happened up to that release... for example, when we remove a mainboard (which also often happens in between releases) that's listed in the next release notes after that. Why should this be different?
I'm okay with waiting until October if that makes this easier, though, not in a rush.

I think it makes more sense to mark the removal to the new 4.11 release notes. Is there any reason to delay this change to after the release?

I don't know, I'd be happy to submit this right away. But since 4.11 is right around the corner (right? Do we have a timeline? IIRC last I heard was "in October" which is sort of over now...) I'm also fine with waiting if people want one final release with "working" MIPS support. I don't think anyone actually cares, though.
Added a blurb to the 4.11 note draft, whoever ends up writing those can rephrase/expand that as desired.

No other board has used it since and nobody is still willing or has the expertise and hardware to maintain it. We have decided that it has become too much of a mainenance burden and the chance of anyone ever reviving it seems too slim at this point. This patch eliminates all MIPS code and MIPS-specific hacks.

Change subject: Remove MIPS architecture ......................................................................
Patch Set 4:
I believe that the 4.11 release is scheduled for roughly November 15. Patrick should be sending out an announcement very shortly.
I agree that probably nobody cares about MIPS support, but it's probably good to leave it in until after the release.

Change subject: Remove MIPS architecture ......................................................................
Remove MIPS architecture
The MIPS architecture port has been added 5+ years ago in order to support a Chrome OS project that ended up going nowhere. No other board has used it since and nobody is still willing or has the expertise and hardware to maintain it. We have decided that it has become too much of a mainenance burden and the chance of anyone ever reviving it seems too slim at this point. This patch eliminates all MIPS code and MIPS-specific hacks.
