+ nand read.raw addr ofs|partition
+ Read page from `ofs' in NAND flash to `addr'. This reads the raw page,
+ so ECC is avoided and the OOB area is read as well.
+
+ nand write.raw addr ofs|partition
+ Write page from `addr' to `ofs' in NAND flash. This writes the raw page,
+ so ECC is avoided and the OOB area is written as well, making the whole
+ page written as-is.
