Hi, This series adds support for the sunxi NAND Flash Controller (NFC) block. These two patches only add support for the basic NAND stuff: - NAND controller operations - SW and HW ECC handling (with both syndrome and normal ECC scheme) If you want support for advanced features you can find it on my github repo [1]: - HW randomization support - per partition ECC/Randomizer to handle bootloader partitions DMA transfers are not supported yet, but I reworked the OOB layout when using the HW ECC scheme to match the one used when accessing the NAND through DMA (the available OOB bytes are placed at the end of the OOB area). Best Regards, Boris [1]https://github.com/bbrezillon/linux-sunxi/tree/sunxi-nand-v7 Changes since v6: - add error message and return code to several wait functions - test wait function return code - rework sunxi ECC mode selection - make use of several helper macros (DIV_ROUND_UP, min, ...) - remove nand-name retrieval and mtd name assignment - remove .owner assignment - fixed several coding style issues Changes since v5: - make use of of_get_nand_ecc_step_size and of_get_nand_ecc_strength - add error messages Changes since v4: - adapt to v2 of "mtd: nand: support ONFI timing mode retrieval for non-ONFI NANDs" series Changes since v3: - removed nand core code modifications from the patch series (submitted separately) - added documentation to the code - forced timeout (a default timeout is used when none is provided by the caller) on controller operations - fixed coding style issues - removed unneeded irq field from the sunxi_nfc struct - fixed several memory leaks - reworked the NFC reset code (to avoid potential garbage config from the bootloader) - made use of ECC_EXCEPTION flag to prevent erased page from generating ECC errors - changed the OOB layout for HW ECC scheme Changes since v2: - merge HW ECC implementation in base implementation patch - fix timing config when interfacing with an ONFI compatible chip Changes since v1: - add HW ECC support - rework NAND timings retrieval (use ONFI timing mode instead of raw timings) - add nand-ecc-level property to specify NAND ECC requirements from DT Boris Brezillon (2): mtd: nand: add sunxi NAND flash controller support mtd: nand: add sunxi NFC dt bindings doc .../devicetree/bindings/mtd/sunxi-nand.txt | 45 + drivers/mtd/nand/Kconfig | 6 + drivers/mtd/nand/Makefile | 1 + drivers/mtd/nand/sunxi_nand.c | 1426 ++++++++++++++++++++ 4 files changed, 1478 insertions(+) create mode 100644 Documentation/devicetree/bindings/mtd/sunxi-nand.txt create mode 100644 drivers/mtd/nand/sunxi_nand.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
