Subject: [PATCH v4 0/2] mtd: nand: fix writing incorrect ECC parity data in OOB region
Date: Tue, 30 Aug 2016 20:35:46 +0800	[thread overview]
Message-ID: <1472560548-30567-1-git-send-email-rogercc.lin@mediatek.com> (raw)

From: RogerCC Lin <rogercc.lin-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>

This series fix chances to write incorrect ECC data which may cause uncorrectable ECC error when reading.

changes since v3:
- use macro for function arguments.

changes since v2:
- use macro for shift operation.

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).
