This patch adds the new IP of Nand Flash Controller(NFC) support on Intel's Lightning Mountain(LGM) SoC. DMA is used for burst data transfer operation, also DMA HW supports aligned 32bit memory address and aligned data access by default. DMA burst of 8 supported. Data register used to support the read/write operation from/to device. NAND controller also supports in-built HW ECC engine. NAND controller driver implements ->exec_op() to replace legacy hooks, these specific call-back method to execute NAND operations. Thank you very much Boris, Martin and Andy for the suggestions and inputs. --- v2: - implement the ->exec_op() to replaces the legacy hook-up. - update the commit message - YAML compatible string update to intel, lgm-nand-controller - add MIPS maintainers and xway_nand driver author in CC v1: - initial version Ramuthevar Vadivel Murugan (2): dt-bindings: mtd: Add YAML for Nand Flash Controller support mtd: rawnand: Add NAND controller support on Intel LGM SoC .../devicetree/bindings/mtd/intel,lgm-nand.yaml | 61 ++ drivers/mtd/nand/raw/Kconfig | 7 + drivers/mtd/nand/raw/Makefile | 1 + drivers/mtd/nand/raw/intel_lgm_nand.c | 740 +++++++++++++++++++++ 4 files changed, 809 insertions(+) create mode 100644 Documentation/devicetree/bindings/mtd/intel,lgm-nand.yaml create mode 100644 drivers/mtd/nand/raw/intel_lgm_nand.c -- 2.11.0
