Subject: [PATCH v2 0/2] mtd: nand: fix writing incorrect ECC parity data in OOB region.
Date: Mon, 29 Aug 2016 19:40:03 +0800 [thread overview]
Message-ID: <1472470803.11041.4.camel@mtkswgap22> (raw)
In-Reply-To: <20160829101006.2b200e0a@bbrezillon>
This series fix chances to write incorrect ECC data which may cause
uncorrectable ECC error when reading.
changes since v1:
- separate patches into 2.
- use shift operator with byte access to avoid endianness conversion
problems.
- follow linux coding style.
The patch passed the test of UBIFS file-system read/write on Mediatek's
RFB. The tested driver is checked-out from LEDE OpenWRT project's
upstream driver, which is pretty much same as nand/next branch upstream
driver(git clone https://git.lede-project.org/source.git).

mtd: nand: fix generating over-boundary ECC data when writing.
mtd: nand: fix chances to create incomplete ECC data when writing.
