+Subject: [PATCH] mtd: rawnand: brcmnand: fix OOB R/W with Hamming ECC
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Hamming ECC doesn't cover the OOB data, so reading or writing OOB shall
+always be done without ECC enabled.
+This is a problem when adding JFFS2 cleanmarkers to erased blocks. If JFFS2
+clenmarkers are added to the OOB with ECC enabled, OOB bytes will be changed
+from ff ff ff to 00 00 00, reporting incorrect ECC errors.
+
+Fixes: 27c5b17cd1b1 ("mtd: nand: add NAND driver "library" for Broadcom STB NAND controller")
