Lately we discovered that the internal driver (fsl-elbc-nand) supports only 1-bit HW ECC. So we would like to switch to ECC_SOFT_BCH (or on-die ECC as I saw some patches in this list recently). Do you know if anybody works on this or are there any patches already? I tried some hacks already because I found that ECC_SOFT is a fallback option if HW ECC is not available. But it seems that there are few bits missing. At least an implemetation of NAND_CMD_RNDOUT. Or am I missing something? Best Regards, Martin Strbacka
