This description seems very incomplete as the symbol
is being used quite a bit and the code the symbol
controls is being deleted as well as the symbol.

Just yesterday I once again raised this issue (see
https://lkml.org/lkml/2014/2/8/248 ). My patch - which dates form May
2013 - removes quite a bit more than Richard's patch.

This code is used in OpenWrt with an out of tree arch code for the
Atheros 231x/531x SoC. [0] I do not think anyone is working on adding
this code to mainline Linux kernel, because of lack of time/interest.

Sorry, we don't maintain out of tree code.

Oleksij, Jonathan do you still working to make ar231x devices work
with upstream, since your posts [1, 2]? Or may be someone from OpenWRT
team would like to add upstream support?

Hi,
my current target was to provide barebox and openocd support.
- ar2313 is already upstream on barebox.
- ar2315-2318 (barebox) awaiting review by Anthony Pavlov.
- openocd (EJTAG) support is ready and i'll push it ASUP.

I hope Jonathan do kernel part. If not, i can provide some work, since i
have testing boards and expiriance on this hardware.

If you need, I can test kernel part, or even do some porting work. I
have some AR231x based boards, e.g. Ubnt LS2 and NS2.

That's a nice toy project, although since there are is an existing
bootloader with sources, I would have shifted the priority towards
getting the kernel support merged such that the bootloader can be used
for something. BTW I sent a few devices to Jonathan, not sure if he
ever got those...

I guess you could start splitting the OpenWrt patches into a format
that makes them suitable for being merged upstream and starting with
the MIPS parts. There might be a bunch of checkpatch.pl cleanup work
to do before getting those submitted.

I will do that if Jonathan does not have a working solution, which he
would like to push upstream. So, let's wait for his reply.

John, can you delay the merging of this patch for a few months, I will
try to prepare the necessary patches to add AR231x architecture to the

ATHEROS_AR231X and the things depending on it, like AHB bus support,
have been discussed for three years now. When will you (re)consider a
patch to remove all currently dead code?

And to state the obvious: AHB bus support, and the other code depending
on ATHEROS_AR231X, can always be re-added once ATHEROS_AR231X gets added
to the tree.

Work in progress, I don't stop it. Just work is progressing slower
than I had planned. I am already cleanup the code (mostly checkpatch
errors and warnings) and send patches to OpenWRT tree. Further I plan
to simplify initialization and I will be ready to send patches
upstream.

I need a couple of weeks for this. Is its reasonable time to not make
a mess of remove/add commits?

That's good to hear.

Removing the code just to re-add it shortly after would indeed be
awkward.

Having this conversation every rc1 is getting a bit silly. Could Jiri
e.a. perhaps set some specific deadline for ATHEROS_AR231X to be
submitted?

Hmm, wouldn't the obvious thing than to add the driver in it's current
form into staging?  Is it well-separated from the rest of  Atheros
WLAN drivers ?

A quick glance at the code shows an include of ar231x_platform.h (which
doesn't exist) and uses of struct ar231x_board_config (ditto). So it
won't build as is and therefor needs work to qualify for staging.

I waited until rc3. Have you seen any activity on this front? If not,
should I resend the patch that removes the code in mainline that depends
on ATHEROS_AR231X (ie, AHB bus support)?

And to repeat the obvious: the removed code can always be re-added once
ATHEROS_AR231X gets actually added to the tree.

Recent activity always could be found in [1]. Now I finish another one
round of cleanups and have a plan to fix several things (you can
always find something that you really want to improve). But if you
insist I could immediately switch to "send upstream" mode. And seems
that this would be better approach.

That excuse has worn a bit thin.  Perhaps Paul should repost his
removal and you can add a revert to the start of your patch series?

[PATCH] [RESEND] ath5k: Remove AHB bus support

[Paul Bolle]

AHB bus support was added in v2.6.38, through commit a0b907ee2a71
("ath5k: Add AHB bus support."). That code can only be build if the
Kconfig symbol ATHEROS_AR231X is set. But that symbol has never been
added to the tree. So AHB bus support has always been dead code.

Let's remove all code that depends on ATHEROS_AR231X. If that symbol
ever gets added to the tree the AHB bus support can be re-added too.

As for me, I do not like such flapping, but you have a final say in

Agreed in case what you have is in a good enough shape. You (and also
others) can still clean up the code in upstream too. So, if it is
mergeable, send it for upstream inclusion now, otherwise I am all for
John to apply the Paul's patch. The unused code has been a way too long
in the tree now.

FYI -- Sergey posted a series to linux-mips on 14 September 2014 that
touches the symbol in question.  For whatever reason, it is posted
there as RFC.

Does this satisfy the interested parties??

Thanks for passing that on.

In case I qualify as an interested party: resolving this by, in short,
making AHB support actually buildable is of course the preferable
solution. 

Whether or not we should drop my patch while waiting for that series to
land in linux-next is not my call. But if it hasn't landed by, say,
about the time v3.18-rc3 is released I might raise this issue again.

I must say that I'm a bit puzzled why people have resisted this rather
small cleanup for years. How did having unbuildable AHB support in
mainline benefit anyone? Couldn't the revert of this cleanup also be
handled out of tree? Note that the revert is only "6 files changed, 3
insertions(+), 294 deletions(-)", while the series is "39 files changed,
3911 insertions(+), 10 deletions(-)".

I think it got added with the notion that the code was "coming soon".
As you have tried to remove it, the "coming soon" refrain continued.

I'm still inclined to merge your patch.  An RFC series posted to
another mailing list doesn't really change my mind.
