 If the NAND FLASH contains random data that is neither erased (all FF) nor
 valid JFFS2 nodes, OFW takes an extremely long time to scan it.

 The problem is that OFW searches the entire NAND surface hoping to find
 JFFS2 nodes; it would be better to give up quickly if an erase block has
 no valid nodes near the beginning.
