config MTD_NAND_ECC_SW_BCH bool "Support software BCH ECC" select BCH default n help This enables support for software BCH error correction. Binary BCH codes are more powerful and cpu intensive than traditional Hamming ECC codes. They are used with NAND devices requiring more than 1 bit of error correction. config MTD_NAND_ARASAN tristate "Support for Arasan Nand Flash controller" depends on HAS_IOMEM && HAS_DMA select BCH help Enables the driver for the Arasan NAND flash controller on Zynq Ultrascale+ MPSoC. |
