+   nand write.raw addr ofs|partition [count]
+      Read or write one or more pages at "ofs" in NAND flash, from or to
+      "addr" in memory.  This is a raw access, so ECC is avoided and the
+      OOB area is transferred as well.  If count is absent, it is assumed
+      to be one page.  As with .yaffs2 accesses, the data is formatted as
+      a packed sequence of "data, oob, data, oob, ..." -- no alignment of
+      individual pages is maintained.
