 JFFS2 has two different kinds of compression in common use - zlib and
 rtime.  The OFW JFFS2 handler does not support the latter.  rtime
 compression is much less commonly encountered in the kinds of files that
 OFW normally boots, but it does show up sometimes, so OFW needs to support
 it.

 There is also a bug in OFW JFFS2 block caching, which results in failures
 to map the entire filesystem in the case where the first erase block on
 the NAND FLASH does not have a summary node.
