ARM: 8888/1: EDAC: Add driver for the Marvell Armada XP SDRAM and L2 cache ECC

2019-08-29T06:58:01Z

Add support for the ECC functionality as found in the DDR RAM and L2 cache controllers on the MV78230/MV78x60 SoCs. This driver has been tested on the MV78460 (on a custom board with a DDR3 ECC DIMM).

EDAC/sifive: Add EDAC platform driver for SiFive SoCs

2019-06-20T18:44:36Z

Add an EDAC driver for SiFive SoCs. The initial version supports ECC event monitoring and reporting through the EDAC framework for the SiFive L2 cache controller. It registers for notifier events from the L2 cache controller driver (arch/riscv/mm/sifive_l2_cache.c) for L2 ECC events.

EDAC/mpc85xx: Prevent building as a module

2019-05-10T18:15:11Z

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! ERROR: ".early_find_capability" [drivers/edac/mpc85xx_edac_mod.ko] undefined! We don't want to export those symbols just for this driver, so make the driver only configurable as a built-in. This seems to have been broken since at least c92132f59806 ("edac/85xx: Add PCIe error interrupt edac support") (Nov 2013).

EDAC/altera: Add separate SDRAM EDAC config

2019-02-26T15:18:57Z

The CONFIG_ALTERA_EDAC Kconfig symbol always enables the SDRAM EDAC functionality. On the newer architectures, however, there are cases where the peripheral EDAC functionality is enabled but SDRAM needs to be disabled. Move SDRAM functions so they can be contained inside the conditional CONFIG. Create new CONFIG option just for SDRAM.

EDAC, i10nm: Add a driver for Intel 10nm server processors

2019-02-02T12:33:18Z

This driver supports the Intel 10nm series server integrated memory controller. It gets the memory capacity and topology information by reading the registers in PCI configuration space and memory-mapped I/O. It decodes the memory error address to the platform specific address by using the ACPI Address Translation (ADXL) Device Specific Method (DSM).

EDAC, skx: Fix randconfig builds in a better way

2018-11-07T21:58:29Z

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".
