[PATCH] arm: msm: remove board file for Nexus One (ie. mahimahi)

[Paul Bolle]

Commit 1b802ff79f03 ("arm: msm: add board file for Nexus One (ie.
mahimahi)") added just board-mahimahi.c. It did not add
board-mahimahi.h, Makefile changes or Kconfig changes.

Four years have passed and this file is still dangling. Remove it.

Untested. But what to test here?

I don't mine if Sapphire gets removed, but I'm working on this one now.. So I don't want it deleted.

Could you ACK that patch, please?

That's good to hear.

This is not something I get to decide. Nevertheless, given that this
file shouldn't have been merged to begin with, I'd appreciate it if some
deadline could be agreed upon.

That being said, I'm not sure how having just this file in mainline
helps your development efforts. It seems it did receive some updates
for, well, treewide stuff. But it surely didn't get build coverage or
runtime testing. So would you lose much if it only remains in your
development tree?

I don't mind if it gets removed, but I wouldn't ACK it's removal ..

I think I merged it actually, but there's no rules about what gets merged. How when what order, etc.
It's all free form.

It's effort to remove it.. Your asking for it to get removed, then re-added.. That sounds
like a fairly large amount of effort vs just leaving it in place.

There do not seem to be formal rules. But there surely are some
requirements for code to be added. One of the requirements is, I think,
that it should build. This file cannot be built: it is not wired into a
Makefile and it also includes, what appears to be, its own header file,
but that header is not part of the tree.

Even the most dubious of code in drivers/staging is expected to "compile
properly"!

Yes, it takes some effort to remove code. And it will also take effort
to re-add that code later. But I think that's a risk one runs with code
that has clearly never been buildable.

The requirements are created by the maintainers.. In this case I would have expected
support for this phone much sooner, and there are in fact patches on the list to support
it which just haven't been merged yet.

But mach-msm isn't staging, different rules apply there.

Heh, different rules you say: "Please send me a patches 
which even didn't compile". This is most relaxed reading
of Documentation/SubmittingPatches that I have heard :-)

Daniel is working on solving that. That should be enough. It is not as
the file is great problem to anybody.

If it is not fixed within year, you may want to retransmit your patch.
