-Subject: [PATCH] mtd: bcm47xxpart: don't fail because of bit-flips
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Bit-flip errors may occur on NAND flashes and are harmless. Handle them
-gracefully as read content is still reliable and can be parsed.
