2020-06-14treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2019-12-20riscv: move sifive_l2_cache.c to drivers/socChristoph Hellwig
The sifive_l2_cache.c is in no way related to RISC-V architecture memory management. It is a little stub driver working around the fact that the EDAC maintainers prefer their drivers to be structured in a certain way that doesn't fit the SiFive SOCs. Move the file to drivers/soc and add a Kconfig option for it, as well as the whole drivers/soc boilerplate for CONFIG_SOC_SIFIVE.

The mpc85xx EDAC driver can be configured as a module but then fails to build because it uses two unexported symbols: ERROR: ".pci_find_hose_for_OF_device" [drivers/edac/mpc85xx_edac_mod.ko] undefined!

2018-11-07EDAC, skx: Fix randconfig builds in a better wayLuck, Tony
It was previously noted that Kconfig complained about unmet dependencies when trying to configure skx_edac together with CONFIG_ACPI=n. First fix for this checked for ACPI when doing select ACPI_ADXL but this required stub functions for the case where ACPI wasn't selected. It also allowed building a driver that didn't actually work for a system that has non-volatile DIMMs. Arnd Bergmann pointed out that the right fix is to make EDAC_SKX "depend on ACPI".

The driver depends on the ADXL component glue and selects it. However, ADXL itself implicitly depends on ACPI and in nonsensical randconfig builds like this: # CONFIG_ACPI is not set CONFIG_ACPI_ADXL=y where ACPI is not enabled, the build fails with: drivers/edac/skx_edac.o: In function `skx_mce_check_error': skx_edac.c:(.text+0xab): undefined reference to `adxl_decode' drivers/edac/skx_edac.o: In function `skx_init': skx_edac.c:(.init.text+0x8bf): undefined reference to `adxl_get_component_names' make: *** [vmlinux] Error 1 Add stubs for that case so that the build succeeds.

Initial target for this driver is the Intel Apollo Lake platform and Denverton micro-server, they use the same internal memory controller IP called Pondicherry2. Memory controller registers are not in PCI config space like earlier Intel memory controllers. For Apollo Lake platform they are accessed via a "side-band" interface, for Denverton micro-server they are access via PCI config space and memory map I/O. This driver is for Apollo Lake and Denverton, but only the Denverton is fully enabled while we wait for the sideband driver. Apollo lake driver and initial cut at Denverton driver by Tony Luck. Extensive cleanup, refactoring and basic verification by Qiuxu Zhuo.

2016-08-21EDAC, skx_edac: Add EDAC driver for SkylakeTony Luck
This is an entirely new driver instead of yet another set of patches to sb_edac.c because: 1) Mapping from PCI devices to socket/memory controller is significantly different. Skylake scatters devices on a socket across a number of PCI buses. 2) There is an extra level of interleaving via the "mcroute" register that would be a little messy to squeeze into the old driver. 3) Validation is getting too expensive. Changes to sb_edac need to be checked against Sandy Bridge, Ivy Bridge, Haswell, Broadwell and Knights Landing.

2015-05-28EDAC: Cleanup atomic_scrub messBorislav Petkov
So first of all, this atomic_scrub() function's naming is bad. It looks like an atomic_t helper. Change it to edac_atomic_scrub(). The bigger problem is that this function is arch-specific and every new arch which doesn't necessarily need that functionality still needs to define it, otherwise EDAC doesn't compile. So instead of doing that and including arch-specific headers, have each arch define an EDAC_ATOMIC_SCRUB symbol which can be used in edac_mc.c for ifdeffery. Much cleaner. And we already are doing this with another symbol - EDAC_SUPPORT. This is also much cleaner than having CONFIG_EDAC enumerate all the arches which need/have EDAC support and drivers. This way I can kill the useless edac.h header in tile too.

2015-01-07EDAC, synps: Add EDAC support for zynq ddr ecc controllerPunnaiah Choudary Kalluri
Add EDAC support for ecc errors reporting on the synopsys ddr controller. The ddr ecc controller corrects single bit errors and detects double bit errors. Selected important-ish notes from the changelog: - I have not taken care of spliting synps_edac_geterror_info function as it adds additional indentation levels and moreover the existing changes were made as part of the v2 review comments - Removed dt binding info as already there is a binding info available under memorycontroller. so, updated ecc info there. - Shortened the prefix "sysnopsys" to "synps" Signed-off-by: Punnaiah Choudary Kalluri <punnaia@xilinx.com> Link: http://lkml.kernel.org/r/a728a8d4678f4dbf9de189a480297c3d@BY2FFO11FD034.protection.gbl [ Boris: massage commit message. ] Signed-off-by: Borislav Petkov <bp@suse.de>
