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 (at91_dt, collie, ep93xx, gemini, h3600, imx_v4_v5, integrator, jornada, moxart, multi_v4t, omap1) were likely not usable with either OABI or EABI and now use EABI instead implicitly, making it more likely that they could work.

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.

I had a plan to change ARMv6 support to no longer coexist in a common kernel with ARMv7 CPUs but instead ARMv5 and below. This would have addressed the problem, but after a recent mailing list discussion, we concluded that an easier approach is to just forbid ARM1136r0 CPU support on SMP-enabled kernels. This mainly affects users of the Nokia N800/N810 tablets using an OMAP2420 SoC, which is the only commercial product with an ARM1136r0 that is still supported by the kernel. The other machines that are still in the same hardware catogory are: - TI OMAP2420 H4 reference board - TI OMAP2430 SDP software development platform - Freescale/NXP i.MX31 Lite Development Kit - Buglabs i.MX31 Bug 1.x prototype - Arm Integrator/AP with CM1136JF-S core module To my knowledge, none of these have any actual users aside from reference boards being used more easily test the platforms. There are also a few ARM1136r1 machines, which implement the ARMv6K SMP support (barriers, atomics and TLS): - Eukrea CPUIMX35 reference platform - Freescale/NXP i.MX35 Product Development Kit - ARM Integrator/CP/IM-LT3 with ARM1136J Core Tile - ARM Realview/EB with ARM1136J Core Tile Again, these are mainly reference implementations rather than actual products, but since they support ARMv6K, they should continue to work correctly in SMP-enabled kernels. For the ARM Core Tile, I have not found a datasheet but instead use the revision based on what the respective virtual models report. All the other ARMv6 platforms use an ARM1176 with ARMv6K, VMSAv7 and Trustzone support. To avoid the broken configuration, annotate the ARM1136 based machines with specific CPU_ARM1136R0 or CPU_ARM1136R2 symbols in Kconfig and make the r0 variants depend on !SMP.

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, chanyge 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 thath already, and the ones that explicitly turned it off before no longer need to.

As far as I can tell, nobody has worked on additional DT conversion in that time, and qemu has in turn deprecated the entire PXA platform. Schedule the remaining board files for removal now, as they are unlikely to be of any help in the future. If anyone wants to revive support for these machines, they can obviously still contribute device tree based code and work on updating the corresponding drivers. Any drivers that are only usable on legacy PXA board files can also get removed along with the boards, or saved by adding devicetree support.

Debian has previously removed the orion/kirkwood kernel binary from the armel distro, but building custom kernels from the Debian source code should keep working, so removing the board files after the 6.12 release ensures that this remains possible for the Debian Trixie release, assuming this will use the 6.12 LTS kernel. Jeremy Peper still plans to convert the Terastation 2 Pro to devicetree in the future, but that can be done even after it is removed.

None of the devicetree conversion actually happened, and qemu has marked the platform as deprecated, so do the same in the kernel now. If anyone is still running one of these four machines and planning to keep updating their kernels, please speak up now so we can adapt the plans as needed. If nobody is found using StrongARM1100 any more, it can be removing during 2025, leaving 6.12-LTS as the last longterm support kernel for it.

The only currently supported configuration uses an ARMv4 StrongARM but still requires building for ARMv3 because of the board design not supporting 16-bit data access. ARMv3 support has been removed in gcc-9, and the gcc-8 release is already old but still supported for building the kernel. The only set of machines that lacks support for 16-bit load/store instructions (Alpha EV5 and older) was recently removed from the kernel. Since there is little hope of this being maintainable much longer, plan to remove it in early 2025 while it is still expected to mostly work.

The Corel NetWinder used to be particular popular in the late 1990s, but was discontinued during the bankruptcy of rebel.com in 2001. The other machine is the DEC (later Intel) EBSA285 evaluation board that was made in small numbers in 1997 for software developers. The footbridge/netwinder platform was the main target for the first Debian 2.0 "Hamm" release on the Arm architecture back in 1998, but was dropped in Debian 6.0 "Squeeze" in 2011, which only supported ARMv4T and higher with the EABI based ports as ARMv4 hardware had fallen already out of use by that time.
