mtd: rawnand: fix build dependency

2019-04-18T06:54:01+00:00

When enabling CONFIG_MTD_NAND_ECC_SW_BCH as a module, the MTD_NAND_ECC_SW_BCH depends on MTD_NAND, but the module controlled by MTD_NAND links against the module controlled by MTD_NAND_ECC_SW_BCH. This leads to the following link failure. aarch64-linux-gnu-ld: drivers/mtd/nand/raw/nand_base.o: in function `nand_cleanup': ../drivers/mtd/nand/raw/nand_base.c:5886: undefined reference to `nand_bch_free' aarch64-linux-gnu-ld: ../drivers/mtd/nand/raw/nand_base.c:5886:(.text+0x9928): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `nand_bch_free' aarch64-linux-gnu-ld: drivers/mtd/nand/raw/nand_base.o: in function `nand_set_ecc_soft_ops': ../drivers/mtd/nand/raw/nand_base.c:5093: undefined reference to `nand_bch_calculate_ecc' aarch64-linux-gnu-ld: ../drivers/mtd/nand/raw/nand_base.c:5093:(.text+0xe914): relocation truncated to fit: R_AARCH64_ADR_PREL_PG_HI21 against undefined symbol `nand_bch_calculate_ecc' aarch64-linux-gnu-ld: ../drivers/mtd/nand/raw/nand_base.c:5093: undefined reference to `nand_bch_calculate_ecc' aarch64-linux-gnu-ld: ../drivers/mtd/nand/raw/nand_base.c:5094: undefined reference to `nand_bch_correct_data' aarch64-linux-gnu-ld: ../drivers/mtd/nand/raw/nand_base.c:5094:(.text+0xe934): relocation truncated to fit: R_AARCH64_ADR_PREL_PG_HI21 against undefined symbol `nand_bch_correct_data' aarch64-linux-gnu-ld: ../drivers/mtd/nand/raw/nand_base.c:5094: undefined reference to `nand_bch_correct_data' aarch64-linux-gnu-ld: ../drivers/mtd/nand/raw/nand_base.c:5148: undefined reference to `nand_bch_init' aarch64-linux-gnu-ld: ../drivers/mtd/nand/raw/nand_base.c:5148:(.text+0xebbc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `nand_bch_init' Rework CONFIG_MTD_NAND_ECC_SW_BCH from tristate to bool, and then link the nand_bch.o file into nand.ko if its enabled.

mtd: rawnand: Clarify Kconfig entry MTD_NAND

2019-04-18T06:54:00+00:00

MTD_NAND is large and encloses much more than what the symbol is actually used for: raw NAND. Clarify the symbol by naming it MTD_RAW_NAND instead. Signed-off-by: Miquel Raynal

mtd: nand: Clarify Kconfig entry for software Hamming ECC entries

2019-04-18T06:54:00+00:00

The software Hamming ECC correction implementation is referred as MTD_NAND_ECC which is too generic. Rename it MTD_NAND_ECC_SW_HAMMING. Also rename MTD_NAND_ECC_SMC which is an SMC quirk in the Hamming implementation as MTD_NAND_ECC_SW_HAMMING_SMC. Signed-off-by: Miquel Raynal

2019-04-18T06:54:00+00:00

There is no point in having two distinct entries, merge them and rename the symbol for more clarity: MTD_NAND_ECC_SW_BCH Signed-off-by: Miquel Raynal

mtd: rawnand: Move drivers for Ingenic SoCs to subfolder

Before adding support for more SoCs and seeing the number of files for these drivers grow, we move them to their own subfolder to keep it tidy. Signed-off-by: Paul Cercueil Signed-off-by: Miquel Raynal

mtd: rawnand: stm32_fmc2: add STM32 FMC2 NAND flash controller driver

2019-02-05T14:39:37+00:00

The driver adds the support for the STMicroelectronics FMC2 NAND Controller found on STM32MP SOCs. This patch is based on FMC2 command sequencer. The purpose of the command sequencer is to facilitate the programming and the reading of NAND flash pages with the ECC and to free the CPU of sequencing tasks. It requires one DMA channel for write and two DMA channels for read operations. Only NAND_ECC_HW mode is actually supported. The driver supports a maximum 8k page size. The following ECC strength and step size are currently supported: - nand-ecc-strength = <8>, nand-ecc-step-size = <512> (BCH8) - nand-ecc-strength = <4>, nand-ecc-step-size = <512> (BCH4) - nand-ecc-strength = <1>, nand-ecc-step-size = <512> (Extended ECC based on Hamming) This patch has been tested on Micron MT29F8G08ABACAH4 and MT29F8G16ABACAH4 Signed-off-by: Christophe Kerello Reviewed-by: Boris Brezillon Signed-off-by: Miquel Raynal
