Many people have done YAFFS on NOR and indeed there are some shipping
products using this.
YAFFS does not do erase suspend, so garbage collection is a bit slow.
Still, it should be fine for testing purposes.
Let's say you have a block size of 64kB.
Each "chunk" needs 512 data bytes + 16 spare bytes = 528 bytes.
Therefore each block can hold 64K/528 = 124 chunks.
So, set chunksPerBlock to 124 and away you go!
