Alpine SoCs supports L1 and L2 single bit correction and two bits detection capability based on ARM implementation. Changes since v2: ----------------- - Use BIT for single bit instead of GENMASK - Use BIT_ULL and GENMASK_ULL for 64bit vector - Fix the mod_name/ctrl_name. Changes since v1: ----------------- - Split into two drivers - Get cpu-mask according to l2-cache handler from devicetree - Remove parameter casting - Use GENMASK() in bit mask - Use FIELD_GET() - Update define description PLRU_RAM -> PF_RAM - Use sys_reg() and read_sysreg_s() - Remove all write/read wrappers - Check fatal field to set if the error correctable or not - Remove un-relevant information from error prints. - Update smp_call_function_single() call function to wait - remove usage of get_online_cpus/put_online_cpus - Use on_each_cpu() and smp_call_function_any() instead of loop with for_each_cpu. - use buffer for error prints and pass to edac API - Remove edac_op_state set - Add for loop to report on repeated errors of the same type - Fix error name of the TLB to be L2_TLB as written in ARM TRM - Minor change in Kconfig - Minor changes in commit message Hanna Hawa (4): dt-bindings: EDAC: Add Amazon's Annapurna Labs L1 EDAC edac: Add support for Amazon's Annapurna Labs L1 EDAC dt-bindings: EDAC: Add Amazon's Annapurna Labs L2 EDAC edac: Add support for Amazon's Annapurna Labs L2 EDAC .../devicetree/bindings/edac/amazon,al-l1-edac.txt | 14 ++ .../devicetree/bindings/edac/amazon,al-l2-edac.txt | 20 +++ MAINTAINERS | 12 ++ drivers/edac/Kconfig | 16 ++ drivers/edac/Makefile | 2 + drivers/edac/al_l1_edac.c | 156 +++++++++++++++++ drivers/edac/al_l2_edac.c | 187 +++++++++++++++++++++ 7 files changed, 407 insertions(+) create mode 100644 Documentation/devicetree/bindings/edac/amazon,al-l1-edac.txt create mode 100644 Documentation/devicetree/bindings/edac/amazon,al-l2-edac.txt create mode 100644 drivers/edac/al_l1_edac.c create mode 100644 drivers/edac/al_l2_edac.c -- 2.7.4
