Subject: Missing support for ECC_SOFT_BCH in fsl-elbc-nand
Date: Fri, 27 Mar 2015 15:13:09 +0100 [thread overview]
Message-ID: <55156575.8080704@nic.cz> (raw)
Hello,
in our product we have Freescale P2020 SoC together with Micron
MT29F2G08ABAEAWP NAND. 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
