Yes. Yaffs doesn't care about block order. You could place blocks from
one nand chip running yaffs, to another chip (as long as the page &
block sizes are the same) in any order that you like, and Yaffs will
scan and run fine. The only exception to this is that block 0 should not
be used, because for each yaffs partition block zero is reserved.
