2022-07-22ARM: sa1100: mark most boards as unusedArnd Bergmann9-0/+19
Most Arm board files are unused and will be removed in early 2023 if no remaining users show up. For the sa1100 platform, the machines that are still in use are: - Russell's Assabet development board - Linus' H3600 iPaq PocketPC - Collie as the only qemu-supported board, to allow testing by others All remaining sa1100 boards are marked to depend on CONFIG_UNUSED_BOARD_FILES to give potential users a last chance to speak up.

2022-07-22ARM: footbridge: mark cats board for removalArnd Bergmann2-1/+1
There are three remaining footbridge boards, as the CO285 and the HP personal server got removed already over the years. Russell still uses his ebsa285, while both Linus and Marc have a NetWinder that they use for testing. Nobody so far replied that they are using cats, so it goes on the long list of machines to be removed in early 2023 if it stays like this.

2022-07-22ARM: mmp: mark all board files for removalArnd Bergmann2-3/+11
The mmp platform supports both ATAGS based board files and DT booting, but it appears that nobody has been interested in board files for a long time. Mark all of them for removal in early 2023 with a dependency on CONFIG_UNUSED_BOARD_FILES, leaving only the DT support for the future, unless someone pops up who uses them.

2022-07-22ARM: ep93xx: mark most board files as unusedArnd Bergmann2-8/+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.

2022-07-22ARM: davinci: mark all ATAGS board files as unusedArnd Bergmann3-20/+8
From an earlier discussion, it appears that the davinci da8xx machines that are still functional have already been converted to DT, while the remaining board files are only kept because nobody has stepped up to remove them. Mark all these boards as 'depends on UNUSED_BOARD_FILES' with the plan to remove them in early 2023 after the next longterm supported kernel is out.

2022-07-22ARM: orion: add ATAGS dependenciesArnd Bergmann6-30/+19
Most of the remaining arm board files in the kernel are unused and will be removed in early 2023 if no users step up. So far I got no user replies about the orion5x and mv78xx0 machines, but these are still supported in the default kernel of the Debian 'armel' (armv5 softfloat) distro, and there is an active project on github that tries to keep some of these machines working, and Mauri Sandberg is working on a DT conversion for the D-Link DNS-323. It appears the Debian-on-Buffalo project has not got the Terastation WXL working in a few years, and the other mv78xx0 machines are just the reference designs, so I assume none of these have remaining users. For the Orion5x family, the same is probably true for its reference implementations (RD88Fxxxxx, DB88F281) and the machines with less than 64MB of memory (WNR854T, WRT350N v2). The remaining nine machines are now scheduled to be kept for at least 2023, hopefully to be replaced with DT based versions. The mv78xx0_defconfig file needs to enable CONFIG_UNUSED_BOARD_FILES to still build, while the other affected defconfig files lose the specific boards.

2022-07-22ARM: pxa: add Kconfig dependencies for ATAGS based boardsArnd Bergmann21-72/+83
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.

2022-07-22ARM: add CONFIG_UNUSED_BOARD_FILESArnd Bergmann1-2/+14
Based on the recent mailing list discussion, most board file support has no remaining users and can be scheduled for removal early next year. If a board is still found to have users, it will remain for this round but users are encouraged to migrate to devicetree based booting where possible. The timing is meant to ensure the next longterm supported kernel still contains all the board files, giving another year of support for potential users that did not speak up and would otherwise be stuck on the v5.15.y longterm kernel from 2021.

2022-07-22ARM: add ATAGS dependencies to non-DT platformsArnd Bergmann8-2/+11
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>
2022-07-22ARM: defconfig: kill remnants of CONFIG_LEDSArnd Bergmann12-22/+42
CONFIG_LEDS was replaced by CONFIG_NEW_LEDS over ten years ago with commit fa8bbb13ab49 ("ARM: use new LEDS CPU trigger stub to replace old one"), but some defconfig files still reference it. Replace it and its sub-options with the corresponding new versions. Some of these machines may not actually have a new-style LED driver, and I did not check them individually as most of the machines are going away soon anyway.

2022-07-22ARM: defconfig: address renamed CONFIG_DEBUG_INFO=yArnd Bergmann43-43/+40
CONFIG_DEBUG_INFO is now implicitly selected if one picks one of the explicit options that could be DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT, DEBUG_INFO_DWARF4, DEBUG_INFO_DWARF5. This was actually not what I had in mind when I suggested making it a 'choice' statement, but it's too late to change again now, and the Kconfig logic is more sensible in the new form. Change any defconfig file that had CONFIG_DEBUG_INFO enabled but did not pick DWARF4 or DWARF5 explicitly to now pick the toolchain default.

2022-07-22ARM: refresh defconfig filesArnd Bergmann95-904/+904
A lot of Kconfig options have changed over the years, and we tend to not do a blind 'make defconfig' to refresh the files, to ensure we catch options that should not have gone away. I used some a bit of scripting to only rework the bits where an option moved around in any of the defconfig files, without also dropping any of the other lines, to make it clearer which options we no longer have.

2022-07-18random: remove CONFIG_ARCH_RANDOMJason A. Donenfeld1-0/+2
When RDRAND was introduced, there was much discussion on whether it should be trusted and how the kernel should handle that. Initially, two mechanisms cropped up, CONFIG_ARCH_RANDOM, a compile time switch, and "nordrand", a boot-time switch. Later the thinking evolved. With a properly designed RNG, using RDRAND values alone won't harm anything, even if the outputs are malicious. Rather, the issue is whether those values are being *trusted* to be good or not. And so a new set of options were introduced as the real ones that people use -- CONFIG_RANDOM_TRUST_CPU and "random.trust_cpu". With these options, RDRAND is used, but it's not always credited. So in the worst case, it does nothing, and in the best case, maybe it helps. Along the way, CONFIG_ARCH_RANDOM's meaning got sort of pulled into the center and became something certain platforms force-select. The old options don't really help with much, and it's a bit odd to have special handling for these instructions when the kernel can deal fine with the existence or untrusted existence or broken existence or non-existence of that CPU capability. Simplify the situation by removing CONFIG_ARCH_RANDOM and using the ordinary asm-generic fallback pattern instead, keeping the two options that are actually used. For now it leaves "nordrand" for now, as the removal of that will take a different route.

The LED controller node is disabled because the leds-turris-omnia driver does not support setting the LED blinking to be controlled by the MCU. The patches for that have now been sent [1], so let's enable the node.

2022-07-18ARM: dts: turris-omnia: configure LED[0] pin function to link/activityMarek Behún1-1/+2
The marvell PHY driver changes the LED[0] pin function to "On - 1000 Mbps Link, Off - Else". Turris Omnia expects that the function is "On - Link, Blink - Activity, Off - No link". Use the `marvell,reg-init` DT property to change the function. In the future, once netdev trigger will support HW offloading, we will be able to have this configured via the combination of PHY driver and leds-turris-omnia driver.

2022-07-18ARM: Marvell: Update PCIe fixupPali Rohár5-9/+27
- The code relies on rc_pci_fixup being called, which only happens when CONFIG_PCI_QUIRKS is enabled, so add that to Kconfig. Omitting this causes a booting failure with a non-obvious cause. - Update rc_pci_fixup to set the class properly, copying the more modern style from other places - Correct the rc_pci_fixup comment This patch just re-applies commit 1dc831bf53fd ("ARM: Kirkwood: Update PCI-E fixup") for all other Marvell ARM platforms which have same buggy PCIe controller and do not use pci-mvebu.c controller driver yet. Long-term goal for these Marvell ARM platforms should be conversion to pci-mvebu.c controller driver and removal of these fixups in arch code.

2022-07-18ARM: dts: lan966x: fix sys_clk frequencyMichael Walle1-1/+1
The sys_clk frequency is 165.625MHz. The register reference of the Generic Clock controller lists the CPU clock as 600MHz, the DDR clock as 300MHz and the SYS clock as 162.5MHz. This is wrong. It was first noticed during the fan driver development and it was measured and verified via the CLK_MON output of the SoC which can be configured to output sys_clk/64. The core PLL settings (which drives the SYS clock) seems to be as follows: DIVF = 52 DIVQ = 3 DIVR = 1 With a refernce clock of 25MHz, this means we have a post divider clock Fpfd = Fref / (DIVR + 1) = 25MHz / (1 + 1) = 12.5MHz The resulting VCO frequency is then Fvco = Fpfd * (DIVF + 1) * 2 = 12.5MHz * (52 + 1) * 2 = 1325MHz And the output frequency is Fout = Fvco / 2^DIVQ = 1325MHz / 2^3 = 165.625Mhz This all adds up to the constrains of the PLL: 10MHz <= Fpfd <= 200MHz 20MHz <= Fout <= 1000MHz 1000MHz <= Fvco <= 2000MHz Fixes: 290deaa10c50 ("ARM: dts: add DT for lan966 SoC and 2-port board pcb8291") Signed-off-by: Michael Walle <michael@walle.cc> Reviewed-by: Kavyasree Kotagiri <kavyasree.kotagiri@microchip.com> Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com> Link: https://lore.kernel.org/r/20220326194028.2945985-1-michael@walle.cc
