So the include needs to be lifted out of there - we lift into tty_driver.h, serdev.h and places that pull asm/termios.h, but none of * linux/uaccess.h (obvious) * net/sock.h (pulls uaccess.h) * linux/{tty,tty_driver,serdev}.h (tty.h pulls tty_driver.h) That leaves us just with the include of UAPI asm/termios.h, which is what <asm/termios.h> will resolve to if we simply remove non-UAPI header.

* | ARM: remove obsolete Makefile.boot infrastructureArnd Bergmann2022-08-181-2/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | There are a number of old Makefile.boot files that remain from the multiplatform conversion, and three that are still in use. These provide the "ZRELADDR", "PARAMS_PHYS" and "INITRD_PHYS" values that are platform specific. It turns out that we can generally just derive this from information that is available elsewhere: - ZRELADDR is normally detected at runtime with the CONFIG_AUTO_ZRELADDR flag, but also needed to be passed to for 'make uImage'. In a multiplatform kernel, one always has to pass this as the $(LOADADDR) variable, but in the StrongARM kernels we can derive it from the sum of $(CONFIG_PHYS_OFFSET) and $(TEXT_OFFSET) that are already known. - PARAMS_PHYS and INITRD_PHYS are only used for bootpImage, which in turn is only used for the pre-ATAGS 'param_struct' based boot interface on StrongARM based machines with old boot loaders. They can both be derived from CONFIG_PHYS_OFFSET and a machine specific offset for the initrd, so all of the logic for these can be part of arch/arm/boot/bootp/Makefile.

* ARM: ep93xx: mark most board files as unusedArnd Bergmann2022-07-221-0/+8
| | | | | | | | | | | | | | | | | | | | | 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. Hartley Sweeten has a MACH_VISION_EP9307 that is still in use. 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.

* ARM: add ATAGS dependencies to non-DT platformsArnd Bergmann2022-07-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

The largest change here is a cleanup of the omap1 platform, which is the final ARM machine type to get converted to the common-clk subsystem. All the omap1 specific drivers are now made independent of the mach/*.h headers to allow the platform to be part of a generic ARMv4/v5 multiplatform kernel. The last bit that enables this support is still missing here while we wait for some last dependencies to make it into the mainline kernel through other subsystems. The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost at the point of allowing multiplatform kernels, this work gets completed here along with a few additional cleanup. At the same time, the s3c24xx and s3c64xx are now deprecated and expected to get removed in the future. The PXA and OMAP1 bits are in a separate branch because of dependencies.

| * ARM: rework endianess selectionArnd Bergmann2022-04-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Choosing big-endian vs little-endian kernels in Kconfig has not worked correctly since the introduction of CONFIG_ARCH_MULTIPLATFORM a long time ago. The problems is that CONFIG_BIG_ENDIAN depends on ARCH_SUPPORTS_BIG_ENDIAN, which can set by any one platform in the config, but would actually have to be supported by all of them. This was mostly ok for ARMv6/ARMv7 builds, since these are BE8 and tend to just work aside from problems in nonportable device drivers. For ARMv4/v5 machines, CONFIG_BIG_ENDIAN and CONFIG_ARCH_MULTIPLATFORM were never set together, so this was disabled on all those machines except for IXP4xx. As IXP4xx can now become part of ARCH_MULTIPLATFORM, it seems better to formalize this logic: all ARMv4/v5 platforms get an explicit dependency on being either big-endian (ixp4xx) or little-endian (the rest). We may want to fix ixp4xx in the future to support both, but it does not work in LE mode at the moment. For the ARMv6/v7 platforms, there are two ways this could be handled a) allow both modes only for platforms selecting 'ARCH_SUPPORTS_BIG_ENDIAN' today, but only LE mode for the others, given that these were added intentionally at some point. b) allow both modes everwhere, given that it was already possible to build that way by e.g. selecting ARCH_VIRT, and that the list is not an accurate reflection of which platforms may or may not work. Out of these, I picked b) because it seemed slighly more logical to me. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

* ARM: ep93xx: remove MaverickCrunch supportArnd Bergmann2021-08-0414-435/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MaverickCrunch support for ep93xx never made it into glibc and was removed from gcc in its 4.8 release in 2012. It is now one of the last parts of arch/arm/ that fails to build with the clang integrated assembler, which is unlikely to ever want to support it. The two alternatives are to force the use of binutils/gas when building the crunch support, or to remove it entirely. According to Hartley Sweeten: "Martin Guy did a lot of work trying to get the maverick crunch working but I was never able to successfully use it for anything. It "kind" of works but depending on the EP93xx silicon revision there are still a number of hardware bugs that either give imprecise or garbage results. I have no problem with removing the kernel support for the maverick crunch." Unless someone else comes up with a good reason to keep it around, remove it now. This touches mostly the ep93xx platform, but removes a bit of code from ARM common ptrace and signal frame handling as well. If there are remaining users of MaverickCrunch, they can use LTS kernels for at least another five years before kernel support ends.

Make sure to request index 0 and 1 in accordance with the SPI MMC DT binding, and add the same GPIOs in machine descriptor tables on all boards that use SPI MMC in board files. The lines are flagged as GPIO_ACTIVE_[LOW|HIGH] as that is what they are, and since we can now rely on the descriptors to have the right polarity, we set the "override_active_level" to false in mmc_gpiod_request_cd() and mmc_gpiod_request_ro().

The irqchip callbacks have been improved so that they can use only the fastpatch callbacks to enable/disable irqs like any normal irqchip, especially the gpiod_lock_as_irq() has been improved to be callable in fastpath context. A bunch of rework had to be done to achieve this but it is a big win since I never liked to restrict this to slowpath. The only call requireing slowpath was try_module_get() and this is kept at the .request_resources() slowpath callback. In the GPIO CEC driver this is a big win sine a single line is used for both outgoing and incoming traffic, and this needs to use IRQs for incoming traffic while actively driving the line for outgoing traffic. - Janusz Krzysztofik improved the GPIO array API to pass a "cookie" (struct gpio_array) and a bitmap for setting or getting multiple GPIO lines at once. This improvement orginated in a specific need to speed up an OMAP1 driver and has led to a much better API and real performance gains when the state of the array can be used to bypass a lot of checks and code when we want things to go really fast. The previous code would minimize the number of calls down to the driver callbacks assuming the CPU speed was orders of magnitude faster than the I/O latency, but this assumption was wrong on several platforms: what we needed to do was to profile and improve the speed on the hot path of the array functions and this change is now completed. - Clean out the painful and hard to grasp BNF experiments from the device tree bindings. Future approaches are looking into using JSON schema for this purpose. (Rob Herring is floating a patch series.) New drivers: - The RCAR driver now supports r8a774a1 (RZ/G2M). - Synopsys GPIO via CREGs driver.

We pass the IRQ numbers as a resource now, and use the virtual mmio base from the already existing resource, rather than relying on the hardwired virtual address from the header file. Some numbers are now hardcoded that came from macros in the past, but for all I can tell, the driver already relied on the specific values.
