请问ok210 linux2.35.7版本nand flash ecc用的1bit ecc,还是8 bit ecc??

楼主，我们nandflash的驱动的源码是不开源的，这在我们销售的时候已经告知了客户，手册也有写。而且如果楼主不更换nandflash芯片的话，nandflash驱动是用不着更改的！也就是说楼主基本不用看nandflash驱动。至于别家的nandflash驱动开源，楼主最好还是去打听下看谁家开发板开源的东西多吧！！！

我们ecc是8bit的，
ecc_layout：
static struct nand_ecclayout s3c_nand_oob_mlc_128_8bit = {
    .eccbytes = 104,
    .eccpos = {
        24,25,26,27,28,29,30,31,32,33,
        34,35,36,37,38,39,40,41,42,43,
        44,45,46,47,48,49,50,51,52,53,
        54,55,56,57,58,59,60,61,62,63,
        64,65,66,67,68,69,70,71,72,73,
        74,75,76,77,78,79,80,81,82,83,
        84,85,86,87,88,89,90,91,92,93,
        94,95,96,97,98,99,100,101,102,103,
        104,105,106,107,108,109,110,111,112,113,
        114,115,116,117,118,119,120,121,122,123,
        124,125,126,127},
    .oobfree =
    {
        {.offset = 2,
         .length = 22
        }
    }
};
