Merge tag 'nand/for-4.19' of git://git.infradead.org/linux-mtd into mtd/next
Pull NAND updates from Miquel Raynal: " NAND core changes: - Add the SPI-NAND framework. - Create a helper to find the best ECC configuration. - Create NAND controller operations. - Allocate dynamically ONFI parameters structure. - Add defines for ONFI version bits. - Add manufacturer fixup for ONFI parameter page. - Add an option to specify NAND chip as a boot device. - Add Reed-Solomon error correction algorithm. - Better name for the controller structure. - Remove unused caller_is_module() definition. - Make subop helpers return unsigned values. - Expose _notsupp() helpers for raw page accessors. - Add default values for dynamic timings. - Kill the chip->scan_bbt() hook. - Rename nand_default_bbt() into nand_create_bbt(). - Start to clean the nand_chip structure. - Remove stale prototype from rawnand.h. Raw NAND controllers drivers changes: - Qcom: structuring cleanup. - Denali: use core helper to find the best ECC configuration. - Possible build of almost all drivers by adding a dependency on COMPILE_TEST for almost all of them in Kconfig, implies various fixes, Kconfig cleanup, GPIO headers inclusion cleanup, and even changes in sparc64 and ia64 architectures. - Clean the ->probe() functions error path of a lot of drivers. - Migrate all drivers to use nand_scan() instead of nand_scan_ident()/nand_scan_tail() pair. - Use mtd_device_register() where applicable to simplify the code. - Marvell: * Handle on-die ECC. * Better clocks handling. * Remove bogus comment. * Add suspend and resume support. - Tegra: add NAND controller driver. - Atmel: * Add module param to avoid using dma. * Drop Wenyou Yang from MAINTAINERS. - Denali: optimize timings handling. - FSMC: Stop using chip->read_buf(). - FSL: * Switch to SPDX license tag identifiers. * Fix qualifiers in MXC init functions. Raw NAND chip drivers changes: - Micron: * Add fixup for ONFI revision. * Update ecc_stats.corrected. * Make ECC activation stateful. * Avoid enabling/disabling ECC when it can't be disabled. * Get the actual number of bitflips. * Allow forced on-die ECC. * Support 8/512 on-die ECC. * Fix on-die ECC detection logic. - Hynix: * Fix decoding the OOB size on H27UCG8T2BTR. * Use ->exec_op() in hynix_nand_reg_write_op().
