Seems to me that you need to know more about the NAND layering
used by the bootloader: What is the layout of the oob/spare
data? Which bytes are used for ECC (and what order), which bytes
are used to hold Yaffs' tags (and what order). Then you can
make linux mtd and yaffs work the same way. Unless Yaffs is
specifically licensed for inclusion in this bootloader, the
producer should be obligated to provided you with the complete
code (GPL).
