-Subject: [PATCH] mtd: rawnand: brcmnand: correctly verify erased pages
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The current code checks that the whole OOB area is erased.
-This is a problem when JFFS2 cleanmarkers are added to the OOB, since it will
-fail due to the usable OOB bytes not being 0xff.
-Correct this by only checking that data and ECC bytes aren't 0xff.
-
-Fixes: 02b88eea9f9c ("mtd: brcmnand: Add check for erased page bitflips")
