[PATCH 00/13] ARM: mark most boards as unused

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Based on the recent mailing list discussion I started [1], I have now
turned the findings into a set of patches that marks most board files as
'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards.

Please double-check the lists for each platform to make sure I got the
right set. The only functional change here is in the Kconfig dependencies,
so I would still apply this as a late fix for the coming merge window,
to give any remaining users the most time to run into this and speak up
in case any of these boards are actually still in use.

[PATCH 01/13] ARM: add ATAGS dependencies to non-DT platforms

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

There are a total of eight platforms that only suppor ATAGS based boot
with board files but no devicetree booting.

For dove, the DT support is part of the mvebu platform, which shares
driver but no code in arch/arm.

Most of these will never get converted to DT, and the majority of the
board files appear to be entirely unused already. There are still known
users on a few machines, and there may be interest in converting some
omap1, ep93xx or footbridge machines over in the future.

For the moment, just add a Kconfig dependency to hide these platforms
completely when CONFIG_ATAGS is disabled, and reorder the priority
of the options: Rather than offering to turn ATAGS off for platforms
that have DT support, make it a top-level setting that determines
which platforms are visible.

The s3c24xx platform supports one machine with DT support, but it
cannot be built without also including ATAGS support, and the
entire platform is scheduled for removal, so leaving the entire
platform behind a dependency seems good enough.

All defconfig files should keep working, as the option remains default
enabled.

[PATCH 02/13] ARM: add CONFIG_UNUSED_BOARD_FILES

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Based on the recent mailing list discussion, most board file support
has no remaining users and can be scheduled for removal early next
year.

If a board is still found to have users, it will remain for this round
but users are encouraged to migrate to devicetree based booting where
possible.

The timing is meant to ensure the next longterm supported kernel
still contains all the board files, giving another year of support
for potential users that did not speak up and would otherwise be

[PATCH 03/13] ARM: pxa: add Kconfig dependencies for ATAGS based boards

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Most of the traditional board files are no longer used by anyone and
will be removed next year, while the DT based machine support remains.

Adding a CONFIG_ATAGS dependency around all the board files means
that they now actaully get disabled when ATAGS support is left out,
and the individual boards that have no known users are marked
as depending on CONFIG_UNUSED_BOARD_FILES, with the plan to remove
them in early 2023 unless someone else shows interest.

Laurence de Bruxelles intends to work on converting the Spitz/Akita/Borzoi
family of Sharp Zaurus SL machines to DT, to make that easier those
remain for the moment.

In addition, the "Gumstix" machine is the one that is supported in
qemu with 256MB of RAM, which makes it particularly nice for testing,
I'm leaving it in hoping that someone can take care of converting it to
DT as well.

Finally, Marc Zyngier is still able to test the Zeus and Viper machines,
so these could be saved as well if anyone wants to conver them to DT.
This seems less likely, so I'm marking them as unused for the time being.

For the defconfig files, both the pxa3xx_defconfig and pxa_defconfig
now only enable the boards that are not marked as unused, while all the
other ones explicitly enable CONFIG_UNUSED_BOARD_FILES to still allow
building the kernels.

[PATCH 04/13] ARM: orion: add ATAGS dependencies

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Most of the remaining arm board files in the kernel are unused and will be
removed in early 2023 if no users step up.  So far I got no user replies
about the orion5x and mv78xx0 machines, but these are still supported
in the default kernel of the Debian 'armel' (armv5 softfloat) distro,
and there is an active project on github that tries to keep some of
these machines working, and Mauri Sandberg is working on a DT conversion
for the D-Link DNS-323.

It appears the Debian-on-Buffalo project has not got the Terastation WXL
working in a few years, and the other mv78xx0 machines are just the
reference designs, so I assume none of these have remaining users.

For the Orion5x family, the same is probably true for its reference
implementations (RD88Fxxxxx, DB88F281) and the machines with less than
64MB of memory (WNR854T, WRT350N v2).

The remaining nine machines are now scheduled to be kept for at least
2023, hopefully to be replaced with DT based versions.

The mv78xx0_defconfig file needs to enable CONFIG_UNUSED_BOARD_FILES
to still build, while the other affected defconfig files lose the
specific boards.

[PATCH 05/13] ARM: davinci: mark all ATAGS board files as unused

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

From an earlier discussion, it appears that the davinci da8xx machines
that are still functional have already been converted to DT, while the
remaining board files are only kept because nobody has stepped up to
remove them.

Mark all these boards as 'depends on UNUSED_BOARD_FILES' with the
plan to remove them in early 2023 after the next longterm supported
kernel is out.

[PATCH 06/13] ARM: ep93xx: mark most board files as unused

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Most of the remaining ARM board files in the kernel have no known users,
and we plan to remove those in early 2023.

For ep93xx, Alexander Sverdlin still has access to the edb93xx family
of reference boards, while Nikita Shubin has a ts7250 and is working on
a device tree conversion for those.

This is a total of nine machine definitions that we will keep
around, but these are all similar machines and are defined in only
two board files. The other six board files now have a dependency on
CONFIG_UNUSED_BOARD_FILES to indicate that they are likely going away.

[PATCH 07/13] ARM: mmp: mark all board files for removal

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The mmp platform supports both ATAGS based board files and DT
booting, but it appears that nobody has been interested in
board files for a long time.

Mark all of them for removal in early 2023 with a dependency
on CONFIG_UNUSED_BOARD_FILES, leaving only the DT support
for the future, unless someone pops up who uses them.

[PATCH 08/13] ARM: footbridge: mark cats board for removal

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

There are three remaining footbridge boards, as the CO285 and the HP
personal server got removed already over the years.

Russell still uses his ebsa285, while both Linus and Marc have a NetWinder
that they use for testing. Nobody so far replied that they are using cats,
so it goes on the long list of machines to be removed in early 2023 if
it stays like this.

[PATCH 09/13] ARM: sa1100: mark most boards as unused

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Most Arm board files are unused and will be removed in early
2023 if no remaining users show up. For the sa1100 platform,
the machines that are still in use are:

 - Russell's Assabet development board
 - Linus' H3600 iPaq PocketPC
 - Collie as the only qemu-supported board, to allow
   testing by others

All remaining sa1100 boards are marked to depend on
CONFIG_UNUSED_BOARD_FILES to give potential users a
last chance to speak up.

[PATCH 10/13] ARM: omap1: add Kconfig dependencies for unused boards

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Legacy board files with no known users are planned to get removed in
early 2023, and this covers the majority of the omap1 boards as well.

According to Tony, the actual users are all on OSK, Nokia770, and
AMS-Delta. Additionally, the sx1 and palmte boards are supported by qemu,
which is convenient for testing, so all five stay around past the initial
board removal.

As omap1 is now part of the multiplatform build and uses the common-clk
framework, it has become easier to convert these to use devicetree
based booting in the future.

[PATCH 11/13] ARM: s3c: mark most board files as unused

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The s3c24xx platform is already scheduled for removal in early 2023,
with s3c64xx meeting the same fate a year later.

Most of the s3c64xx board files appear to be unused, as the better
maintained ones already got converted to DT. The main exception is
the Wolfson Cragganmore board, which remains in use as the reference
design for Wolfson/Cirrus devices. As the other boards get removed,
this one stays around along with the DT based machines.

The s3c6400_defconfig file now disables the unused boards, while the
s3c24xx defconfig files all turn on CONFIG_UNUSED_BOARD_FILES to
remain usable.

[PATCH 11/13] ARM: s3c: mark most board files as unused

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The s3c24xx platform is already scheduled for removal in early 2023,
with s3c64xx meeting the same fate a year later.

Most of the s3c64xx board files appear to be unused, as the better
maintained ones already got converted to DT. The main exception is
the Wolfson Cragganmore board, which remains in use as the reference
design for Wolfson/Cirrus devices. As the other boards get removed,
this one stays around along with the DT based machines.

The s3c6400_defconfig file now disables the unused boards, while the
s3c24xx defconfig files all turn on CONFIG_UNUSED_BOARD_FILES to
remain usable.

[PATCH 12/13] ARM: iop32x: mark as unused

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The iop32x platform has recently been converted to be part of
the multiplatform configuration, and it should be possible to
keep it alive for longer by making it boot from devicetree like
we did for the related ixp4xx platform.

However, it appears that no users remain at this point, so just
mark the entire platfor depending on CONFIG_UNUSED_BOARD_FILES,
with the intention of removing it in early 2023.

If any users remain, please speak up now.

[PATCH 13/13] ARM: cns3xxx: add CONFIG_UNUSED_BOARD_FILES dependency

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Krzysztof Halasa has kept the cns3xxx platform working for a long time
but has moved away from working on it. The OpenWRT port was dropped in
2020, and support for the Gateworks Laguna platform never made it into
the mainline kernel, which only supports the reference design.

Further, the ARM11MPCore has an unresolved issue with instruction cache
coherency, and removing support for the remaining platforms using this
core would be the easiest solution.

Mark the entire platform as unused now, to be removed in early 2023 if
no users show up.

Note that although I have the machines (I do remember which side of
the attic they are stored), I don't have much bandwidth to actually
revive them (assuming I could remember the RedBoot runes to kick them
into action).

I can only renew my offer to unload them on a willing victim, but I
have the feeling that there are no takers.

Alexander,

MACH_VISION_EP9307

I also have a EDB9302 eval boad, a Sim.One board and a Contec Micro9 board. But I have not powered those on for quite a while. They did work last time I used them.

MACH_SIM_ONE
MACH_MICRO9

That sounds to me like it fits in the 'unused' category, so I left it
marked that way.
Let me know if you think we should keep them for now.

Also, do you have any additional thoughts on longterm viability of
ep93xx, especially
plans for how long Vision EP9302 kernel updates will get distributed
to users, and
whether it makes sense to convert it to DT?

I do know about one actively used TS7250 based board. It is going to be
still used for some time. However, I don't have the HW with me, but may
be available when the BSP will be refurbished.

Ok, thanks for the information. It sounds like an increasing argument
for doing a DT conversion after all. How often does the BSP get a new
kernel? I think Nikita's DT conversion for ts7250 (see [1]) shouldn't
be too hard to port from 5.11 to 5.20+, as most of the patches just
introduce driver support. The multiplatform conversion in 5.19 hopefully
made things a bit easier but likely also requires a few extra changes.

Last time it was from 2.6.2X to 4.14 LTS ...

I could easily get updated the customer's board to the DT if at least
one ep93xx is in tree (as it is based on TS7250).

However, I cannot predict when the new BSP (with new Kernel) will be
required ....

I'm happy with this, because with these other boards gone it might
actually be viable to transition this to DT.

Both the ts7250/bk3 and the edb93xx variants are going to stay
for the moment, based on the feedback I got from Alexander and
Nikita, so this part is fine.

> However, I cannot predict when the new BSP (with new Kernel) will be

I see that 4.14-lts will stop getting updates in early 2024, so I guess
this is the latest point to upgrade in order to still receive security fixes
(assuming that you actually update the production kernel periodically
for updated 4.14.y releases).

This still gives us the choice between two approaches that let us
retire the ep93xx board files in 2024:

a) do the DT conversion over the next 18 months (hopefully
    quicker) and let you update to that when the 4.14 release
    ends, with the option of further updates later.

b) do nothing until the LTS release in late 2023 and retire
   all of ep93xx in early 2024, leaving users with LTS  kernel
   fixes until at least 2027 (depending on how long this release
   gets maintained).

If everyone is fine with the limitations of b), that is obviously
the easier path, otherwise a) should not be that hard either.

I feel a bit nostalgic about ts7250, as it was my very first "embedded"
Linux board, so i think it needs a proper retirement.

So let me finish the full conversion on the top of 5.20+ and then we can
think if it's suitable for plan "a". It won't take long, as i have a
bootable BSP on branch [2].
