If you have to move the ECC anyway, there really isn't a further compatibility problem with moving the JFFS2 bytes as well. 0-1 : BB marker 2-23 : Free space (JFFS2 will use) 24-63 : 4 x 10 bytes of ecc. This way, if the default ecc layout patch that I submitted is ever accepted, the code in this patch can be removed.
