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).
