Devres now requires T: 'static, which conflicts with shmem::Object using
Devres<SGTableMap<T, C>> without that bound. Resolve by adding 'static
as a supertrait to DriverObject and DeviceContext, which does not
restrict any current use cases since DriverObject is always implemented
on owned, refcounted types and DeviceContext is a sealed marker trait
with only unit-type implementors.

If DriverObject (or DeviceContext) ever becomes lifetime-parameterized
(e.g. via a GAT for TTM backed objects), the 'static supertrait can be
relaxed at that point.

Merge tag 'soc-arm-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC platform updates from Arnd Bergmann:
"The 32-bit Arm platforms are a bit more interesting this time: I
refreshed an earlier series to mark code as deprecated that does have
the tendency of getting in the way of cleanups and new features but
has close to zero users. Among these are:

- 22 of the remaining 28 legacy board files that predate the current
devicetree based descriptions, using old chips from Intel and
Marvell. The remaining six board files are for TI OMAP1 and Samsung
s3c64xx chips and all still have known users.

- support for Cortex-M3/M4/M7 and ARM1136r0 CPU cores and the 25
machines based on these. These all use devicetree but the CPU
support causes disproportional work. Most of them are just
reference boards, the notable exceptions being the Nokia N800/N810
tablet and the Buglabs BUG platform.

- be8, be32, oabi and iwmmxt userspace binaries, which were mostly
associated with the platforms now scheduled for removal and are
increasingly problematic to support with modern toolchains.

Nothing is actually removed at this point, to ensure that any
remaining users continue to have the 7.3-LTS for a while longer.
Patches for removal are currently being tested.

Other updates include a continued work to convert GPIO number based
interfaces to descriptors, a patch to restore little-endian mode on
the one Arm platform (ixp4xx) that only worked in big-endian mode
recently, and some minor cleanups and bugfixes"

- Consolidate delay timer calibration

The construct of having a define in a header requires that
architectures provided asm/timex.h for no reason. Also the function
name for reading the delay timer is confusing at best.

Use a config switch to enable that functionality and rename the
function to delay_read_timer() to make the purpose clear.

ARM: platform and feature deprecation for 7.3

This is an attempt to bring the source code to the state that we discussed
back in 2024, regarding a timeline for deprecating and removing features,
in particular platforms and ABIs that are basically unused and are
also getting in the way of maintenance.

The earlier consensus was to remove these features in 2025 or 2026
after the corresponding LTS kernel release. I would suggest pushing
these to early 2027 now, see the patch description for details on
each one:

- all board files that are still not converted to DT
(except for OMAP1 and S3C)

- iWMMXt FPU support

- ARMv6/ARM1136r0 (not ARMv6K/ARM1136r1/ARM1176) along with the
OMAP24xx and i.MX31 SoCs using it

- Cortex-M3/M4/M7 based microcontroller support
(stm32, imxrt, lpc18xx, samv7)

- LSI Axxia platform

- OABI, OABI-compat and NWFPE are confined to StrongARM based
builds and scheduled for removal once StrongARM is gone.

- DEPRECATED_PARAM_STRUCT, which was originally scheduled for
removal in 2006 (!)

The ARCH_S3C64XX platform was scheduled for removal in 2024, but is
still actively used and will get removed once Mark Brown stops using
it. The OMAP1 platform has some remaining boardfiles and is expected to
get converted to DT.

Big-endian ARMv7 CPU support is not scheduled for removal but marked
as broken the same way as ARM64 has, to reduce the need for testing
unused configurations. This may be removed in the future if arm64 does
it as well. Note that big-endian ARMv5 support is can still be
enabled since the patches to revive little-endianm mode are still
fresh.

Regarding actually removing the code, I would suggest linux-7.4 (January
2027), removing both the board files and any drivers that have either
become newly unused or were missed in a previous machine removal series,
followed by removing support for then unused CPUs a release later.

ARM: mark Cortex-M3/M4/M7 based boards as deprecated

The Cortex-M3/M4/M7 cores were designed as a replacement for the earlier
ARM7TDMI and ARM9TDMI microarchitectures used in older microcontrollers.

At the moment, Linux can run these cores either when they are integrated
into a larger SoC, or as standalone microcontrollers. While there was
a lot of development work going into Cortex-M support from 2011 to 2016,
this largely stopped when it became clear that Zephyr and other RTOS
had taken over that market. To date, the only Cortex-M based based
microcontroller boards supported upstream are reference implementations.

Schedule these for removal after the next LTS kernel, so if any users
remain that want to update their kernels, they can stay on that
version for a few years before having to maintain the platform support
out of tree.

With no remaining users and support getting removed from future compilers,
there seems little point in keeping iwmmxt around much longer.

On the other hand, the iwmmxt support in the kernel rarely gets in the
way, so there is little cost, so set a removal date of early 2027 for
the moment. If anyone is still using this, it can be extended as long
there is binutils support.

This configuration option is for the older boot method that preceeded

not because there are any users left.

ARM: turn CONFIG_ATAGS off by default

Only a very small number of machines remain that rely on
traditional board files with the ATAGS boot data instead
of devicetree, and we have not accepted new ones for
a decade.

Most of the remaining ones are on their way out of the
kernel, but the Kconfig option that controls ATAGS
is still enabled by default.

To reflect the actual status of ATAGS support and alert
the remaining users of upstream and out-of-tree platforms
with this, change it to being default-disabled and
add a dependency on CONFIG_EXPERT.

The board specific defconfig files that rely on ATAGS
are changed to turn on both EXPERT and ATAGS if they
were not doing that already, and the ones that explicitly
turned it off before no longer need to.

ARM: limit OABI support to StrongARM CPUs

As discussed on the mailing lists, there is no way to build OABI userspace
binaries any more since gcc-4.8, and now support is also getting dropped in
binutils, which will make it impossible to build pure OABI kernels at some
point in the future.

I found no evidence of anyone still sing OABI userspace on embedded systems
that keep getting kernel updates, but there are a few desktop-class machines
that date back to the 1990s using Intel StrongARM processors that were
supported by old versions of Debian, Red Hat or the official Corel
Netwinder distribution.

Add a much stricter Kconfig dependency for both native OABI and OABI_COMPAT
enabled kernels, only allowing either of them to be selected when building
a kernel that targets a StrongARM based machine.

ARM: use CONFIG_AEABI by default everywhere

On ARMv4 and ARMv5, the default is still to build for OABI, with
CONFIG_AEABI disabled, even though distros and toolchains no longer
support OABI as a target.

Change the default to EABI for all architecture levels and change
the defconfig entries as follows:

- All machines that used to explicitly enable EABI can drop that line now
- Machines that are likely to actually use old distros and had NWFPE
enabled in combination with OABI (rpc, footrbridge, netwinder,
assabet, neponset) explicitly turn it on now.
- Machines that already had both EABI and NWFPE disabled in defconfig
(spear3xx, spear6xx) were likely not usable with either OABI or
EABI and now use EABI instead implicitly, making it more likely that
they could work.
