+ 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.
