There is no defconfig file for gemini, which has lead to a lot
of bitrot. This makes the broken board files, the gpio implementation
and the reset logic work again, and fixes the build warnings
that got introduced with the changes to the readl/writel prototypes.

From: Arnd Bergmann @ 2013-01-04 14:41 UTC (permalink / raw)
To: linux-arm-kernel
The gemini platform has not seen any updates from its
maintainer since 2010, and has no defconfig file, which
has lead to bitrot in a number of places:
* System restart has been broken for a long time despite
repeated attempts from Russell to get the obvious
fix at least acknowledged by someone who can test it.
* The platform still uses mach/gpio.h, which has been
deprecated for some time, and since Kconfig does not
select NEED_MACH_GPIO_H, it actually failed to build
because of this.
* A change to asm/io.h introduced a number of compiler
warnings for gemini specific code that confuses
physical and virtual addresses.
This removes gemini support entirely under the assumption
that nobody uses it on mainline kernels. Of course, if
there are still active users out there, they should let
us know so we can put support back in and get it better
tested.

From: Arnd Bergmann @ 2013-01-04 14:41 UTC (permalink / raw)
To: linux-arm-kernel
With the Cortina Gemini platform gone, nothing in ARM uses
the Faraday 526 CPU core support any more. There is at least
one other platform using this (Moschip MCS814x), but the
efforts to get that merged into mainline appear to have
stalled.
If someone still needs this code, please speak up now,
otherwise we will remove it now. Of course there is
always the option to revert this patch if we need it
again later.

The gemini platform is quite broken at the moment due to bitrot,
here are the two suggested solutions. We should either apply the
first patch or the other two, depending on whether anyone still
uses this.
Ulli was last actively working on this about two years ago,
so I assume that he has moved on, but if he or anyone else
is still interested in keeping Gemini alive, any patches
and testing are very welcome. Without a maintainer however,
I see no point in keeping it.
The fa526 CPU support is currently only used on Gemini,
but Florian had some patches last year for it, so he might
still need it. If there are still plans to get MCS814x
or another fa526 based platform merged into mainline,
we can keep this around, but unless I see a timeline
for this, I would prefer to remove it for now. It should
be trivial to revert that patch and bring it back if
it's needed for a new platform.
Arnd Bergmann (3):

Arnd: I suggest you rebase and apply this series, sans the FA526
removal as I hear it may now be used on the Moxart.
I patched the generic time code for gemini in october last year
and noone has yet bothered to even test it!
Yours,
Linus Walleij

I guess you mean just the middle patch then? The first one
was actually applied.
On the other hand, I did make a patch now to enable multiplatform
support for gemini that I was planning to send for review.
Florian, what is the status of gemini in openwrt? From what I can
tell, it's stuck at linux-3.9 [1], which is probably why nobody has
tested Linus' timer code. It's not clear if anyone is still interested
in it, but I also don't see a reason why any of the patches in
the openwrt repository couldn't just get merged (with some trivial
changes in a few cases).

There is no defconfig file for gemini, which has lead to a lot
of bitrot. This makes the broken board files, the gpio implementation
and the reset logic work again, and fixes the build warnings
that got introduced with the changes to the readl/writel prototypes.

From: Arnd Bergmann @ 2013-01-04 14:41 UTC (permalink / raw)
To: linux-arm-kernel
The gemini platform has not seen any updates from its
maintainer since 2010, and has no defconfig file, which
has lead to bitrot in a number of places:
* System restart has been broken for a long time despite
repeated attempts from Russell to get the obvious
fix at least acknowledged by someone who can test it.
* The platform still uses mach/gpio.h, which has been
deprecated for some time, and since Kconfig does not
select NEED_MACH_GPIO_H, it actually failed to build
because of this.
* A change to asm/io.h introduced a number of compiler
warnings for gemini specific code that confuses
physical and virtual addresses.
This removes gemini support entirely under the assumption
that nobody uses it on mainline kernels. Of course, if
there are still active users out there, they should let
us know so we can put support back in and get it better
tested.

From: Arnd Bergmann @ 2013-01-04 14:41 UTC (permalink / raw)
To: linux-arm-kernel
With the Cortina Gemini platform gone, nothing in ARM uses
the Faraday 526 CPU core support any more. There is at least
one other platform using this (Moschip MCS814x), but the
efforts to get that merged into mainline appear to have
stalled.
If someone still needs this code, please speak up now,
otherwise we will remove it now. Of course there is
always the option to revert this patch if we need it
again later.

From: Arnd Bergmann @ 2013-01-04 15:30 UTC (permalink / raw)
To: linux-arm-kernel
There is no defconfig file for gemini, which has lead to a lot
of bitrot. This makes the broken board files, the gpio implementation
and the reset logic work again, and fixes the build warnings
that got introduced with the changes to the readl/writel prototypes.

2013-01-04 15:30 ` [PATCH, RFC 3/3] ARM: remove fa526 CPU support Arnd Bergmann
1 sibling, 0 replies; 14+ messages in thread
From: Arnd Bergmann @ 2013-01-04 15:30 UTC (permalink / raw)
To: linux-arm-kernel
The gemini platform has not seen any updates from its
maintainer since 2010, and has no defconfig file, which
has lead to bitrot in a number of places:
* System restart has been broken for a long time despite
repeated attempts from Russell to get the obvious
fix at least acknowledged by someone who can test it.
* The platform still uses mach/gpio.h, which has been
deprecated for some time, and since Kconfig does not
select NEED_MACH_GPIO_H, it actually failed to build
because of this.
* A change to asm/io.h introduced a number of compiler
warnings for gemini specific code that confuses
physical and virtual addresses.
This removes gemini support entirely under the assumption
that nobody uses it on mainline kernels. Of course, if
there are still active users out there, they should let
us know so we can put support back in and get it better
tested.

From: Arnd Bergmann @ 2013-01-04 15:30 UTC (permalink / raw)
To: linux-arm-kernel
With the Cortina Gemini platform gone, nothing in ARM uses
the Faraday 526 CPU core support any more. There is at least
one other platform using this (Moschip MCS814x), but the
efforts to get that merged into mainline appear to have
stalled.
If someone still needs this code, please speak up now,
otherwise we will remove it now. Of course there is
always the option to revert this patch if we need it
again later.

I did not have actually hardware to port MCS814x to anything else than
MCS8140 (real ARM 926EJS core), while MCS8142 and MCS8144 actually use a
FA626 (not 526) core. Added in CC are Imre and Gabor who actually worked
on the Gemini machine and might be able to either give their go for
removal, or fix the issues.
