As promised, here are the removal patches for a few Arm platforms and
the c6x architectures. I have already merged the patches to remove the
picoxcell and efm32 platforms. The five in this series are the ones I
have not received patches for, so I went ahead and did them myself.
There are three other platforms that we had discussed removing but
that I ended up not including:
- Hisilicon 32-bit server chips (hip01/hip04), these are certainly
obsolete, but the related Kunpeng506/509 platform is still and
active and will be merged soon. It shares a lot of the device
drivers, so we can revisit this one after the new code is merged
and it is clearer which code is unused.
- WonderMedia wm86xx/vt8500 apparently still occasially has users
asking about the platform, as noted by Alexey Charkov in a
private follow-up.
- I did patches to remove asm9260, but ended up not including them
here, as I had not heard back from Oleksij. The platform is
related to NXP i.MX28 (mach-mxs), so it shares a number of
drivers with that and has very little platform specific code.
Overall, all the platforms getting removed this time are ones
that had upstream support funded by the SoC manufacturer, but
did not have a hobbyist community that took over when the original
contributors stopped getting paid for maintenance.

From: Arnd Bergmann <arnd@arndb.de>
As promised, here are the removal patches for a few Arm platforms and
the c6x architectures. I have already merged the patches to remove the
picoxcell and efm32 platforms. The five in this series are the ones I
have not received patches for, so I went ahead and did them myself.
There are three other platforms that we had discussed removing but
that I ended up not including:
- Hisilicon 32-bit server chips (hip01/hip04), these are certainly
obsolete, but the related Kunpeng506/509 platform is still and
active and will be merged soon. It shares a lot of the device
drivers, so we can revisit this one after the new code is merged
and it is clearer which code is unused.
- WonderMedia wm86xx/vt8500 apparently still occasially has users
asking about the platform, as noted by Alexey Charkov in a
private follow-up.
- I did patches to remove asm9260, but ended up not including them
here, as I had not heard back from Oleksij. The platform is
related to NXP i.MX28 (mach-mxs), so it shares a number of
drivers with that and has very little platform specific code.
Overall, all the platforms getting removed this time are ones
that had upstream support funded by the SoC manufacturer, but
did not have a hobbyist community that took over when the original
contributors stopped getting paid for maintenance.

* [PATCH 1/5] c6x: remove architecture
@ 2021-01-20 12:48 ` Arnd Bergmann

Cc: Arnd Bergmann, Mark Salter, Aurelien Jacquiot, linux-c6x-dev
From: Arnd Bergmann <arnd@arndb.de>
The c6x architecture was added to the kernel in 2011 at a time when
running Linux on DSPs was widely seen as the logical evolution.
It appears the trend has gone back to running Linux on Arm based SoCs
with DSP, using a better supported software ecosystem, and having better
real-time behavior for the DSP code. An example of this is TI's own
Keystone2 platform.
The upstream kernel port appears to no longer have any users. Mark
Salter remained avaialable to review patches, but mentioned that
he no longer has access to working hardware himself. Without any
users, it's best to just remove the code completely to reduce the
work for cross-architecture code changes.
Many thanks to Mark for maintaining the code for the past ten years.

* [PATCH 1/5] c6x: remove architecture
@ 2021-01-20 12:48 ` Arnd Bergmann

From: Arnd Bergmann @ 2021-01-20 12:48 UTC (permalink / raw)
To: linux-arm-kernel, linux-kernel, soc
Cc: Aurelien Jacquiot, linux-c6x-dev, Arnd Bergmann, Mark Salter
From: Arnd Bergmann <arnd@arndb.de>
The c6x architecture was added to the kernel in 2011 at a time when
running Linux on DSPs was widely seen as the logical evolution.
It appears the trend has gone back to running Linux on Arm based SoCs
with DSP, using a better supported software ecosystem, and having better
real-time behavior for the DSP code. An example of this is TI's own
Keystone2 platform.
The upstream kernel port appears to no longer have any users. Mark
Salter remained avaialable to review patches, but mentioned that
he no longer has access to working hardware himself. Without any
users, it's best to just remove the code completely to reduce the
work for cross-architecture code changes.
Many thanks to Mark for maintaining the code for the past ten years.

* [PATCH 2/5] ARM: remove sirf prima2/atlas platforms
@ 2021-01-20 12:48 ` Arnd Bergmann
0 siblings, 0 replies; 29+ messages in thread
From: Arnd Bergmann @ 2021-01-20 12:48 UTC (permalink / raw)
To: linux-arm-kernel, linux-kernel, soc; +Cc: Arnd Bergmann, Barry Song
From: Arnd Bergmann <arnd@arndb.de>
The SiRF Prima2 and Atlas platform code was contributed by Cambridge
Silicon Radio (CSR) after aquiring the original SiRF company, and
maintained by Barry Song. CSR was subsequently acquired by Qualcomm,
who no longer have an interest in maintaining the SoC platform but
instead have released more recent SoCs for the same market in the
Snapdragon family.
As Barry is no longer working for the company, nobody else there
wants to maintain it, and there are no third-party users, the
best way forward seems to be to completely remove it.
Thanks to Barry for maintaining the platform for the past ten years.

* [PATCH 2/5] ARM: remove sirf prima2/atlas platforms
@ 2021-01-20 12:48 ` Arnd Bergmann
0 siblings, 0 replies; 29+ messages in thread
From: Arnd Bergmann @ 2021-01-20 12:48 UTC (permalink / raw)
To: linux-arm-kernel, linux-kernel, soc; +Cc: Barry Song, Arnd Bergmann
From: Arnd Bergmann <arnd@arndb.de>
The SiRF Prima2 and Atlas platform code was contributed by Cambridge
Silicon Radio (CSR) after aquiring the original SiRF company, and
maintained by Barry Song. CSR was subsequently acquired by Qualcomm,
who no longer have an interest in maintaining the SoC platform but
instead have released more recent SoCs for the same market in the
Snapdragon family.
As Barry is no longer working for the company, nobody else there
wants to maintain it, and there are no third-party users, the
best way forward seems to be to completely remove it.
Thanks to Barry for maintaining the platform for the past ten years.
Cc: Barry Song <baohua@kernel.org>

* [PATCH 3/5] ARM: remove zte zx platform
@ 2021-01-20 12:48 ` Arnd Bergmann
0 siblings, 0 replies; 29+ messages in thread
From: Arnd Bergmann @ 2021-01-20 12:48 UTC (permalink / raw)
To: linux-arm-kernel, linux-kernel, soc; +Cc: Arnd Bergmann, Jun Nie, Shawn Guo
From: Arnd Bergmann <arnd@arndb.de>
The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with
Baoyou Xie and Shawn Guo subsequently becoming maintainers after the
addition of the 64-bit variant.
However, the only machines that were ever supported upstream are the
reference designs, not actual set-top-box devices that would benefit
from this support. All ZTE set-top-boxes from the past few years seem
to be based on third-party SoCs. While there is very little information
about zx296702 and zx296718 on the web, I found some references to other
chips from the same family, such as zx296716 and zx296719, which were
never submitted for upstream support. Finally, there is no support for
the GPU on either of them, with the lima and panfrost device drivers
having been added after work on the zx platform had stopped.
Shawn confirmed that he has not seen any interest in this platform for
the past four years, and that it can be removed.
Thanks to Jun and Shawn for maintaining this platform over the past
five years.

The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with
Baoyou Xie and Shawn Guo subsequently becoming maintainers after the
addition of the 64-bit variant.
However, the only machines that were ever supported upstream are the

to be based on third-party SoCs. While there is very little information
about zx296702 and zx296718 on the web, I found some references to other
chips from the same family, such as zx296716 and zx296719, which were
never submitted for upstream support. Finally, there is no support for
the GPU on either of them, with the lima and panfrost device drivers
having been added after work on the zx platform had stopped.
Shawn confirmed that he has not seen any interest in this platform for
the past four years, and that it can be removed.
Thanks to Jun and Shawn for maintaining this platform over the past
five years.

* [PATCH 4/5] ARM: remove tango platform
@ 2021-01-20 12:48 ` Arnd Bergmann
0 siblings, 0 replies; 29+ messages in thread
From: Arnd Bergmann @ 2021-01-20 12:48 UTC (permalink / raw)
To: linux-arm-kernel, linux-kernel, soc
Cc: Arnd Bergmann, Marc Gonzalez, Mans Rullgard
From: Arnd Bergmann <arnd@arndb.de>
The smp8758 (tango4) SoC was the last generation of set-top-box chips
to come out of Sigma Designs, and support was added by Marc Gonzalez
and Måns Rullgård between 2015 and 2017, before the company went out of
business and the products were abandoned.
The chip is used in some set-top-boxes such as the Popcorn Hour A-500,
which could have seen some adoption by hobbyists. This has not happened
in the past four years, and support for the more widely used MIPS based
SoCs was never merged at all.
Thanks to Marc and Måns for maintaining for the past years even after the
death of the platform.

* [PATCH 4/5] ARM: remove tango platform
@ 2021-01-20 12:48 ` Arnd Bergmann
0 siblings, 0 replies; 29+ messages in thread
From: Arnd Bergmann @ 2021-01-20 12:48 UTC (permalink / raw)
To: linux-arm-kernel, linux-kernel, soc
Cc: Mans Rullgard, Arnd Bergmann, Marc Gonzalez
From: Arnd Bergmann <arnd@arndb.de>
The smp8758 (tango4) SoC was the last generation of set-top-box chips
to come out of Sigma Designs, and support was added by Marc Gonzalez
and Måns Rullgård between 2015 and 2017, before the company went out of
business and the products were abandoned.
The chip is used in some set-top-boxes such as the Popcorn Hour A-500,
which could have seen some adoption by hobbyists. This has not happened
in the past four years, and support for the more widely used MIPS based
SoCs was never merged at all.
Thanks to Marc and Måns for maintaining for the past years even after the
death of the platform.

* [PATCH 5/5] ARM: remove u300 platform
@ 2021-01-20 12:48 ` Arnd Bergmann
0 siblings, 0 replies; 29+ messages in thread
From: Arnd Bergmann @ 2021-01-20 12:48 UTC (permalink / raw)
To: linux-arm-kernel, linux-kernel, soc; +Cc: Arnd Bergmann, Linus Walleij
From: Arnd Bergmann <arnd@arndb.de>
The Ericsson U300 platform was one of two ARM929 based SoC platforms for
mobile phones in ST-Ericsson after the merger of Ericsson with ST-NXP
into ST-Ericsson, the other one being the ST Nomadik.
The platform was not widely adopted in Linux based systems and was
replaced with the far superior ST-Ericsson U8500 in 2011, but Linus
Walleij kept maintaining the code for the whole time.
Linus continues to use the Nomadik machine, but decided to drop
u300 from the kernel as part of this year's spring cleaning.
Thanks for having maintained it all these years.

* [PATCH 5/5] ARM: remove u300 platform
@ 2021-01-20 12:48 ` Arnd Bergmann
0 siblings, 0 replies; 29+ messages in thread
From: Arnd Bergmann @ 2021-01-20 12:48 UTC (permalink / raw)
To: linux-arm-kernel, linux-kernel, soc; +Cc: Linus Walleij, Arnd Bergmann
From: Arnd Bergmann <arnd@arndb.de>
The Ericsson U300 platform was one of two ARM929 based SoC platforms for
mobile phones in ST-Ericsson after the merger of Ericsson with ST-NXP
into ST-Ericsson, the other one being the ST Nomadik.
The platform was not widely adopted in Linux based systems and was
replaced with the far superior ST-Ericsson U8500 in 2011, but Linus
Walleij kept maintaining the code for the whole time.
Linus continues to use the Nomadik machine, but decided to drop
u300 from the kernel as part of this year's spring cleaning.
Thanks for having maintained it all these years.

I was planning to do this but you got there first :)
The reason I cannot work on it anymore is that the device
requires a special signing server to flash new kernels and
I don't have access to that, and we never created a U-boot or
similar for this device so anything needed to go in through
that flashing tool.

Yes, I'll pick up the five patches in this series directly, while the
drivers should go through the other subsystem trees, so please
apply the pinctrl/gpio patches to your respective tree.
