[Yaffs] required blocks calculation for Checkpoint

Hi Charles,

In function yaffs_CalcCheckpointBlocksRequired, I see the following remark:
/* Round up and add 2 blocks to allow for some bad blocks, so add 3 */

I want to use yaffs over NOR device. Since NOR devices don't have bad blocks, will it be OK if I will not add those 2 blocks (to save space on my yaffs partition)?

Thanks
