+Change it by merging continuous sections:
+S1 1-5
+ECC 6-8

+S3 25-37

+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.
