This patchset adds the support for the STMicroelectronics FMC2 NAND flash controller found on STM32MP SOCs.
This patchset supports: - the polling mode feature - a maximum 8k page size - following ECC strength and step size - 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 patchset has been tested on Micron MT29F8G08ABACAH4 (8-bit SLC NAND).
