If you look in the yaffs/direct directory you will find a bootloader example  
(source and doc) that will give you a boot data stream off a file in a yaffs 
device (built with mkyaffs image or written to NAND by YAFFS). This 
bootloader can be executed off NOR to place the image in RAM.

Otherwise, just follow Nick's guidelines. If you have a large NAND array, 
then you might want to consider partitioning the NAND as two devices, putting 
the boot code on one and the rest of the fs on the other. This speeds up scan 
time (and hence boot time).

Hope that helps.
