| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement ECC correctable and uncorrectable error handling for EDU reads. If ECC correctable bitflips are encountered on EDU transfer, read page again using PIO. This is needed due to a NAND controller limitation where corrected data is not transferred to the DMA buffer on ECC error. This applies to ECC correctable errors that are reported by the controller hardware based on set number of bitflips threshold in the controller threshold register, bitflips below the threshold are corrected silently and are not reported by the controller hardware.
