I mean the patch 10/11 "mtd: add the ecc info for some full-id nand chips". What does the above result for the other chips? Does it get populated at runtime? ~Vikram

Does it get populated at runtime? it does not influence other nand , except the full-id nand case. yes, it gets populated at runtime. thanks Huang Shijie
