From: Arnd Bergmann <arnd@arndb.de>
In the 7.3 kernel, I marked a number of platforms and features as
deprecated, with the plan to keep these around for the LTS kernel, but
remove them in 7.4, see [1].
Cleaning out the deprecated platform code has turned into a larger effort
than I expected, currently standing at 300 patches, with a lot of them
still in need of being split up into smaller ones, see [2] for a current
snapshot.
The first series here removes just the bits in arch/arm/mach-*/, plus
the portions that directly depend on the removed Kconfig symbols where
these are trivial to remove.
The parts that are not included are those that remove architectural
features and device drivers that become unused after this part. Some of
those may also make their way into 7.4, but at this point I would target
7.5 for most of them, to keep the dependencies simple.
This also gives everyone a chance to voice their objections in case
that some of the removed platform code does have active users after all,
before all the corresponding drivers are gone.

From: Arnd Bergmann <arnd@arndb.de>
Footbridge was deprecated in 7.3 to be removed along with the other
StrongARM platforms and most remaining board files.
The main machine here is the NetWinder, which was a popular Arm based
desktop PC in the late 1990s and contributed to Arm's later success as
an embedded Linux platform, but was discontinued over 25 years ago and
is no longer all that useful.
I previously tried to convert this to devicetree in a sensible way but
gave up due to the platform being too different from modern SoC based
targets.

From: Arnd Bergmann <arnd@arndb.de>
The Freescale i.MX31 was an early SoC based on the ARM1136r0 CPU core. It
was used in the Bug Labs modular computer but ultimately much less
popular than most other i.MX SoCs.
As the ARM1136r0 support is causing a lot of extra maintenance effort
to keep alive and there are no known users, remove i.MX31 in order to
allow removing support for that CPU core altogether.
The related i.MX35 is based on a slightly newer ARM1136r1 CPU core that
does not have this problem, so there is no reason to remove that.

From: Arnd Bergmann <arnd@arndb.de>
The NXP LPC18xx and LPC43xx microcontrollers are the more modern
version of the classic LPC32xx line, but they lack memory management
units.
These microcontrollers all remain in production as of 2026, but
there are no known users running Linux on them.
The platform was marked deprecated in the 7.3-LTS release, which
will remain supported for a few more years.
Remove support for both LPC18xx and LPC43xx.

From: Arnd Bergmann <arnd@arndb.de>
The Arm mps2 platform is the reference implementation for Arm
microcontrollers and is useful for testing but not expected to be used
as a production device.
With all the Cortex-M based products gone, there is no longer a need
for a reference platform either, so remove it as well.

SoCs using ARM926 and Cortex-A CPUs as well as a number of
microcontrollers. Only a single one of those MCUs currently
has Linux support, and has no known users.
The samv7 platform was deprecated in Linux-7.3LTS, which will
remain supported a while longer after it is gone from mainline.

From: Arnd Bergmann <arnd@arndb.de>
The initial Axxia port was contributed by LSI in 2014, but never completed
after the sale of the business unit to Intel, which kept supporting the
bulk of the drivers in their own downstream BSP.
The downstream work has also ended now, and there is no realistic chance
that anyone would rewrite it all into an upstreamable port.
Remove it now that the 7.3LTS release is out and can be used as the
base for one more downstream rebase of the downstream patches if needed.

I don't see netwinder.rst in any of the single patches.
Should it be in one of them?
[snip]
> arch/arm/configs/netwinder_defconfig | 88 -
Same for netwinder_defconfig.
If netwinder is going away, can all of
Documentation/arch/arm/nwfpe/ also go away?
Or do all of these come later (in phase 2 or 3)?
thanks.

gag. I hadn't received patch 02/13 yet. Didn't realize that. :(

If some user really want to keep this platform around and it
willing to invest time in testing, I do not think it is hard to
convert it to device tree using an LLM.
But if there are no users, away it goes.

I have one of those machines and it boot mainline but I
certainly consider it a paperweight at this point, I can't use
it for anything useful.

I ACK this based on the number of refactorings I did on this
to remove the static GPIO assignments, I'm really tired of
doing them if no-one benefits.

nwfpe is used on all OABI platforms, not just netwinder, so
the patch to remove that comes in the next series after removing
OABI. See
https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc.git/commit/?id=ff375183fe225b79de700f004181405ff6a739cc
for the draft patch.

Note that Sashiko skipped reviewing this patch, because it exceeded

This drops the layout switch but keeps "mrvl,sa1100-rtc" in
sa1100_rtc_dt_ids[] and in bindings/rtc/sa1100-rtc.yaml, so a DT with
that compatible would now silently get the MMP register offsets instead
of the SA1100 ones.

"embedded into PXA2xx chips" is better.
The RTC_DRV_SA1100 help text a bit earlier in the patch also still says
"built into your SA11x0 or PXA2xx CPU".

Yes, I have a patch for that in

My initial search was incomplete(used _MPS2_ instead of _MPS2).
We also have timer/clocksource driver:

Ah ok, then discard my followup message. I assume you would have the timer

This one is interesting: this was already the behavior before
my patch, as CONFIG_ARCH_SA1100 is mutually exclusive with all
other targets. That obviously wasn't the intention of the code.
I've removed the sa1100_rtc_dt_ids[] entry now.

Do you want to drop all the samv7 platform compatibles from at91.yaml?
Are there non-Linux users using DT?

I failed to 'steal' a J-Slate when I left Tadpole.
(a very early 'tablet' computer with an LCD panel)
So I don't have one either.
Although that ran VxWorks and rtx-windows (after I patched bits so it worked!).

I see that zephyr uses DT here, but it uses an incompatible
set of bindings, see
https://github.com/zephyrproject-rtos/zephyr/tree/main/dts/arm/atmel
I'm dropping the references from the binding now, and also from
Documentation/arch/arm/microchip.rst, which I had missed earlier.

Indeed, same for me: my first paid job involved both SA1100 and
the i486 compatible AMD Élan SoC that was also removed this year.

I still do possess a LogicPD i.MX31 Lite board, which boots the upstream
kernel, but there is no plan to maintain it further.

Since there is no known users of these pretty old NOMMU platforms in
the Linux kernel, it should be safe to drop them from maintenance.

Likewise, I have a NetWinder machine which has occasionally booted a
mainline kernel, along with fairly current buildroot initramfs. It has
been surprisingly smooth sailing, even the bx/bl compiler troubles seem
to have been sorted out these days.
It's a bit sad to see it go, in particular since it all works. But the
reality is that nobody seems to be running this hardware anymore, and
there is no community of active users anymore.

If this patch has to be reposted, here is the feedback of my AI coding
assistant (based on an LLM and hence may be wrong):
----------------------------------------------------------------------
Overview
--------
This patch removes the Acorn RiscPC platform (ARCH_RPC), the oldest
32-bit ARM machine supported in mainline Linux (originally ARMv3 ARM610,
later StrongARM SA-110). Because RiscPC hardware requires -march=armv3
(discontinued in GCC 9) due to bus limitations, deprecating and removing
it paves the way to clean out legacy ARMv3 support from the kernel.
Removing RiscPC also represents a major architectural milestone for
arch/arm: with SA-1100 (patch 1), Footbridge (patch 2), and RiscPC
(patch 3) removed, COMMON_CLK, SPARSE_IRQ, and USE_OF (Device Tree)
become unconditionally selected for all 32-bit ARM targets, and legacy
headers mach/io.h and mach/memory.h are eliminated.
Overall, this is a very welcome cleanup, but there are a few missed
references, orphaned symbols, and stale comments that should be addressed.
Issues & Observations
---------------------
1. Missed arch/arm/Makefile cleanup
Patch 03 deletes the entire directory arch/arm/mach-rpc/, but does not
touch arch/arm/Makefile. As a result, two orphaned entries remain:
makefile
machine-$(CONFIG_ARCH_RPC) += rpc
machdirs-$(CONFIG_ARCH_RPC) += arch/arm/mach-rpc
Furthermore, machdirs-$(CONFIG_ARCH_RPC) was the very last user of
machdirs- in arch/arm/Makefile (after Footbridge and SA-1100 are removed
in patches 1 & 2):
makefile
# legacy platforms provide their own mach/*.h headers globally,
# these three are mutually exclusive
machdirs-$(CONFIG_ARCH_FOOTBRIDGE) += arch/arm/mach-footbridge
machdirs-$(CONFIG_ARCH_RPC) += arch/arm/mach-rpc
machdirs-$(CONFIG_ARCH_SA1100) += arch/arm/mach-sa1100
KBUILD_CPPFLAGS += $(patsubst %,-I$(srctree)/%/include,$(machdirs-y))
Once RiscPC is gone, the entire machdirs- inclusion block can and should
be removed from arch/arm/Makefile.
2. Missed ARCH_ACORN reference in lib/fonts/Kconfig
The patch deletes config ARCH_ACORN from arch/arm/Kconfig and removes
#ifdef CONFIG_ARCH_ACORN from
lib/fonts/font_acorn_8x8.c
, but missed
lib/fonts/Kconfig:74
:
kconfig
config FONT_ACORN_8x8
bool "Acorn console 8x8 font" if FONTS
depends on FRAMEBUFFER_CONSOLE || DRM_PANIC
default y if !SPARC && !FONTS && ARM && ARCH_ACORN
Because ARCH_ACORN is removed, this default can never trigger and the
reference should be cleaned up.
3. Orphaned ARCH_RPC reference in arch/arm/mm/Kconfig
In
arch/arm/mm/Kconfig:281-282
:
kconfig
config CPU_SA110
bool
select CPU_32v3 if ARCH_RPC
select CPU_32v4 if !ARCH_RPC
Since ARCH_RPC is removed, select CPU_32v3 if ARCH_RPC references a
non-existent symbol. If CPU_SA110 remains temporarily (before the
architectural cleanup in 7.5), this should be simplified to select CPU_32v4.
4. Dead code in arch/arm/kernel/atags_compat.c
With CONFIG_ARCH_ACORN removed from arch/arm/Kconfig, two blocks in
arch/arm/kernel/atags_compat.c
are now dead code:
Lines 150–157: #ifdef CONFIG_ARCH_ACORN / if (machine_is_riscpc())
memory bank tagging.
Lines 186–194: #ifdef CONFIG_ARCH_ACORN ATAG_ACORN translation.
These blocks should be removed as part of this patch.
5. Stale comments
arch/arm/include/asm/io.h:207-209
:
c
/*
* Now, pick up the machine-defined IO definitions
*/
#if IS_ENABLED(CONFIG_PCMCIA) || defined(CONFIG_PCI)
CONFIG_NEED_MACH_IO_H and #include <mach/io.h> were removed, leaving
this comment describing generic PCI/PCMCIA I/O limits.
arch/arm/boot/bootp/Makefile:21
: # guess an initrd location if possible is left dangling right before
ifdef INITRD_OFFSET after all initrd_offset-$(CONFIG_...) logic has been
stripped out.
6. Floppy driver & arch/arm/include/asm/floppy.h status
The patch removes the ARM MFM AND FLOPPY DRIVERS entry from MAINTAINERS:
diff
-ARM MFM AND FLOPPY DRIVERS
-M: Ian Molton <spyro@f2s.com>
-S: Maintained
-F: arch/arm/include/asm/floppy.h
-F: arch/arm/mach-rpc/floppydma.S
While
floppydma.S
was deleted,
arch/arm/include/asm/floppy.h
was left in the tree.
On ARM, floppy support requires ARCH_MAY_HAVE_PC_FDC, which was selected
only by Footbridge and RiscPC.
With both gone, no ARM board selects ARCH_MAY_HAVE_PC_FDC.
Furthermore, asm/floppy.h references IRQ_FLOPPYDISK and DMA_FLOPPY,
which no longer exist on ARM.
Either
arch/arm/include/asm/floppy.h
and config ARCH_MAY_HAVE_PC_FDC in arch/arm/Kconfig should be deleted
in this patch, or noted if intentionally deferred to the 7.5 driver cleanup.
7. Good changes & verification
block/partitions/Kconfig: Dropping default y if ARCH_ACORN while keeping
ACORN_PARTITION available under PARTITION_ADVANCED is correct; users can
still inspect/mount Acorn media on modern architectures.
drivers/tty/vt/keyboard.c: Clean removal of !defined(CONFIG_ARCH_RPC)
from the raw keyboard scan handler.
Elimination of NEED_MACH_IO_H and NEED_MACH_MEMORY_H: Very clean removal
across arch/arm/Kconfig, arch/arm/include/asm/io.h,
arch/arm/include/asm/memory.h, and arch/arm/mm/mmu.c.
Minor Typo in Commit Message
text
The Acorn Risc PC is the oldest still support Arm machine in the kernel,
originally shipped with an ARMv3 ARM610 support in 1994, it later allowed
faster StrongARM CPUs.
"oldest still support Arm machine" -> "oldest still supported Arm machine"
"with an ARMv3 ARM610 support" -> "with ARMv3 ARM610 support" or "with

Most of this was already discussed, but there are two additional
changes that I made based on it.

I have this in the patch that removes acornfb. It could go into
either one, but I felt it fits better there

Also explained already that I preferred removing CPU_32v3 along
with CPU_SA110 in a later patch, not together with ARCH_RPC.

There is both a u-boot and buildroot config for i.MX RT1050,
I also do basic regression testing on this platform. I understand the
need to depreciate no-MMU, but it's sad to see them go.
If it helps at all to remove i.MX RT1050 there are only 11 commits
adding it that are from Giulio Benetti and I.
For i.MX RT1170 only 3 commits by me which only got partially
added. See
Commit: fff65226b229 ("pinctrl: freescale: Add i.MXRT1170 pinctrl
driver support")
I also occasionally test the stm32f429-disco as I have one.
