ARM: pxa: add Kconfig dependencies for ATAGS based boards

2022-07-22T11:11:21Z

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.

Pull more ARM multiplatform updates from Arnd Bergmann: "The second part of the multiplatform changes now converts the Intel/Marvell PXA platform along with the rest. The patches went through several rebases before the merge window as bugs were found, so they remained separate.

ARM: pxa: convert to multiplatform

2022-05-07T20:56:17Z

PXA is now ready to be built into a single kernel with all the other ARMv5 platforms, so change the Kconfig bit to finish it off. The mach/uncompress.h support is the last bit that goes away, getting replaced with the normal DEBUG_LL based approach. Signed-off-by: Arnd Bergmann

ARM: pxa: remove Intel Imote2 and Stargate 2 boards

2022-02-28T14:08:14Z

I have no reason to believe these boards have any more users and I haven't tested them for several years. Removing them may simplify other changes to the various PXA boards people still care about. The recent conversion of pxa2xx_spi to GPIO descriptors for example had to update this board despite no one caring or testing. Great boards that got me started in kernel development, RIP!

ARM: pxa: remove Compulab pxa2xx boards

2020-05-25T22:10:57Z

As these boards have no more users nor testers, and patching them has become a burden, be that because of the PCI part or the MTD NAND support, let's remove them. The cm-x300 will for now remain and represent Compulab boards at its best in the PXA department.

These boards are now fully ported to device-tree, so the old implementation can go away. The defconfig needs downstream quirks anyway, so we can just remove it from mainline. Signed-off-by: Daniel Mack Signed-off-by: Robert Jarzmik

Pull ARM updates from Russell King: "Included in this update: - Florian Fainelli noticed that userspace segfaults caused by the lack of kernel-userspace helpers was hard to diagnose; we now issue a warning when userspace tries to use the helpers but the kernel has them disabled. - Ben Dooks wants compatibility for the old ATAG serial number with DT systems. - Some cleanup of assembly by Nicolas Pitre. - User accessors optimisation from Vincent Whitchurch. - More robust kdump on SMP systems from Yufen Wang. - Sebastian Andrzej Siewior noticed problems with the SMP "boot_lock" on RT kernels, and so we convert the Versatile series of platforms to use a raw spinlock instead, consolidating the Versatile implementation. We entirely remove the boot_lock on OMAP systems, where it's unnecessary. Further patches for other systems will be submitted for the following merge window. - Start switching old StrongARM-11x0 systems to use gpiolib rather than their private GPIO implementation - mostly PCMCIA bits. - ARM Kconfig cleanups. - Cleanup a mostly harmless mistake in the recent Spectre patch in 4.20 (which had the effect that data that can be placed into the init sections was incorrectly always placed in the rodata section)" * tag 'for-4.21' of git://git.armlinux.org.uk/~rmk/linux-arm: (25 commits) ARM: omap2: remove unnecessary boot_lock ARM: versatile: rename and comment SMP implementation ARM: versatile: convert boot_lock to raw ARM: vexpress/realview: consolidate immitation CPU hotplug ARM: fix the cockup in the previous patch ARM: sa1100/cerf: switch to using gpio_led_register_device() ARM: sa1100/assabet: switch to using gpio leds ARM: sa1100/assabet: add gpio keys support for right-hand two buttons ARM: sa1111: remove legacy GPIO interfaces pcmcia: sa1100*: remove redundant bvd1/bvd2 setting ARM: pxa/lubbock: switch PCMCIA to MAX1600 library ARM: pxa/mainstone: switch PCMCIA to MAX1600 library and gpiod APIs ARM: sa1100/neponset: switch PCMCIA to MAX1600 library and gpiod APIs ARM: sa1100/jornada720: switch PCMCIA to gpiod APIs pcmcia: add MAX1600 library ARM: sa1100: explicitly register sa11x0-pcmcia devices ARM: 8813/1: Make aligned 2-byte getuser()/putuser() atomic on ARMv6+ ARM: 8812/1: Optimise copy_{from/to}_user for !CPU_USE_DOMAINS ARM: 8811/1: always list both ldrd/strd registers explicitly ARM: 8808/1: kexec:offline panic_smp_self_stop CPU ...
